Apologies if this is already stated somewhere, but are these wagons readily convertible to 21 mm as per all other IRM rolling stock. This doesn't look to be the case from the photos, and I'm assuming Heljan only made cosmetic changes to a model they already produce?

Seen that too John-Athlone and Galway Easons don’t seem to stock any railway magazines. 

Was in the Galway branch yesterday and was delighted to find single copies of both RM and BRM. This was the first time I found railway magazines there in a long, long time. 

It's interesting to hear that there are no issues running on Peco bullhead code 75 track. I wonder if, despite both being labelled 'code 75', there are some dimensional differences between Peco and SMP rail/chairs. I came across a post on Rmweb a while back in which a poster claimed that Peco bullhead track is not 'finescale'. This would suggest some differences - and I'm pretty sure he was not talking about the gauge, given that some OO gauge layouts are billed as finescale (handmade track etc). 

Hi folks,

I was under the impression that the wheels on modern RTR locos are likely to be compatible with most types of track - apart from P4 standards. However, I've tried running a MM 121 on Marcway SMP code 75 bullhead flexitrack and Exactoscale bullhead basses with the same SMP rail. In both cases, there's a very obvious 'thunk, thunk, thunk, thunk....' sound as the loco runs along the track. Evidently, the wheel flanges are hitting the chairs. Has anybody out there replaced the wheels on their IRM and MM locos with finescale alternatives, without going all the way to P4 tolerances?

As far as I know, the Connemara Railway only plans to run less than 10km of the old line, but a railway to Clifden would, couple with effective  onward transport, allow for easy, environmentally friendly, and hopefully cheap, access to areas like Roundstone, Ballyconneeley, historic areas like the site of the Marconi station and Alcock and Brown’s landing site, etc. as well as providing access to Moycullen, Oughterard, etc.

In theory, this would be fantastic. However, although much of the old trackbed still exists, there are houses, gardens and other private property on top of it in places now.

I came across this chap's YouTube channel recently, and it's very informative for anybody interested in finescale modelling and scratchbuilding. He has a few videos in which he describes how to use Templot and 3D printing/laser cutting to produce bespoke trackwork, and this looks like a viable option for 21 mm track. I've never used Templot, but my understanding is that it includes 21 mm templates, so it should be straight forward to produce 21 mm track and points. Has anybody here tried this approach?

Marks Models have the MM 121 loco decoder

Thank you - completely missed that!

Any decent 8 or 21 pin decoder will do. IRM and Murphy models recommended only using their decoders for warranty guarantees, but its over 12 months now since these locos were released. I use a mix of different decoders in my locos, and the only trouble I've had is with hornby 8 pin decoders. Lais dcc decoders are great value for money. I've used more that 30 so far over the last 5-8 years and all still going fine. 

Hope this helps. 

Thanks Beano. I'm very new to DCC and wasn't aware that generic decoders could be used - very helpful!

Hi folks,

I have been collecting Irish locos over the last couple of years, with a view to building a layout in due course. Unfortunately, at the time of buying the locos, I didn't give any consideration to DCC decoders - on the assumption that I would be able to pick them up at a later stage. Alas, not so. I've been able to find decoders for my 071 and 201, but it seems that A class and 121 decoders are out of stock everywhere. I'm assuming 141/181 decoders will be available when these locos are re-released, but does anybody know if the A class and 121 decoders are still available anywhere? Or, if they'll become available any time soon? Also, I should probably emphasise that it's only the decoders that I'm looking for, not the sound chips.

Many thanks!

@Fiacra I took a few photos to show you what’s possible. This is a Murphy / Bachmann CIE coach from way back when, converted many moons ago to 21mm gauge, P4 Profile to run on Adavoyle. I think the wheels are Alan Gibson on 28mm axles and I suspect a jig was used to get everything square. Under the brass bolster plate there is a brass bush but the details are not visible. The screws are likely M2. the original bogie has just been cut down the centre and widened with the plate, nothing fancy. I hope this gives you some ideas.

 

Lovely work! Very helpful - thanks TimO!

Thanks TimO - that is very welcome news! I only have a couple of the original MM mk2d's and have been using them as conversion guinea pigs ahead of the new batch arriving. But, if the new bogies are prototype width, that will make things a lot easier.

MJT Carriage Compensation Units can be assembled for EM P4 and 21mm. Brassmaster make nice units also.

Thanks for this info Rich. The MJT rigid bogie frame was my first foray into brass kits, but despite my trepidation it was quite straight forward. However, CCUs look like they would require a much more delicate touch - might be a step too far for me at this stage. I'll pick one up though, and see how it goes. 

Well, I'm in a position to answer the question myself now - it being 'with some difficulty'. There may be an easier way, but I ended up having to remove the body from the chassis, and even then, there was a lot of blindly poking, squeezing, and forcing the attachment jaws out of position, before the bogie came away. Clearly designed to be robust rather than for easy removal. I wonder if the new batch of mk2d's will be designed in the same way?

My reason for wanting to remove the bogies in the first place is to regauge the models for EM track. I've mentioned this in a previous post, but I've opted to go EM gauge as a compromise between 00 and 21mm (the availability of track, points etc, being large part of the decision). Unfortunately, the bogies on the mk2d's are not wide enough for a simple axle swap-out. My original intention was to replace the whole bogie with an MJT brass bogie frame (using the original MM bogie sides as cosmetic attachments). Alas, it seems the MJT bogies are also strictly 00 gauge - something I only realised after constructing one and attempting to install a DCC Concepts EM gauge wheelset. That's no criticism of MJT, as they don't advertise the rigid bogie kits as anything other than 00 - I suppose I assumed there might be enough wiggle room in them to accept EM gauge axles.

So, it looks like the only way forward is to cut up the MM bogies and use plasticard to rebuild them to a suitable width. That shouldn't be too difficult, but if anybody knows of another way of approaching this, I'm all ears.

Many thanks! 

Apologies for such a basic question, but how does one go about removing the bogies from a MM mk2d? I thought they might disconnect with a bit of force, but that starts pulling the whole chassis away from the body, so it must require a more nuanced approach. 

Thanks for any help!

A question for the IRM folks. Now that Mk2 delivery is on the horizon, are there plans to sell the scale-Irish-width B4 bogies as separate packs (e.g. to replace the narrower bogies on MM carriages)?

Outstanding layout! The bridge in particular is stunning - how was the stonework created?

The details are still placeholders, so only the header information is correct, in that case, its "5203 Irish Railways Mark 2d Standard - Irish Rail (Orange roof)" - everything else is placeholder information, pending any details from Mr. Murphy.

Perfect - thank you!

I received the 'ready to purchase' notifications for the mk2D's that I pre-ordered. However, I would like to get some clarification before I pay. The carriages are listed as e.g '5203 Irish Railways Mark 2d Standard - Irish Rail (Orange roof)', which I take to mean IR tippex livery with orange roof (exactly what I'm looking for). However, the description section for all of the 2D's states 'CIE Supertrain Livery'. Can anybody here shed any light on the matter?

Many thanks!

Fantastic - thanks for all of this information Mayner!

Apologies in advance for adding a very basic question to this thread. Am I correct to assume that a single 15v source can power multiple point motors (if they will only be thrown one at a time)? If this is the case, how should one go about connecting everything? Presumably it's not as simple as connecting all of the wiring directly to the power source. Is there such a thing as a breakout box that can receives the two wires from the power source, and can then relay this to multiple point motors?

@FiacraA few photo of the motor mounting would help?

If the motor is mounted directly under the points this could restrict movement as the actuation rod is short and cannot bend for short point movement! So if the motor is mounted with, say a 20mm thick mdf spacer between the motor and point, this would allow the actuating rod to bend a bit and allow the switch to operate correctly??

Eoin.

Thanks Eoin - this seems to be the most common solution to this problem. However, the actuating rod on these seep motors is fairly strong stuff - even cutting them takes a fair bit of effort. I'm not so sure it would bend even slightly, given the extra distance if mounted as suggested. I'll certainly give it a try though!

Its simple i used that setup for Lochty The trick with the SEEPs  is to convert the fixing holes into slots(file or burr)and don't tighten the screws just leave them slightly floating that way you have enough movement for the switch,Andy

Ah, indeed - that sounds like just trick! Thanks Andy.

Hi folks,

Following on from a post I made last year regarding the possibility of modelling Irish railways in EM gauge, I decided to build a small test track consisting of a single, branching line (i.e. three lengths of track connected to a turnout) on which to test run some re-gauged rolling stock - dip my toes in the world of gauge conversion before committing to a full layout. I’m using an EM Gauge Society Peco turnout and I purchased a Gaugemaster PM-4 Seep point motor to control the switch rails and the polarity of the frog. Alas, I’ve already hit a bump in the road. It looks like the throw of the switch rails in the Peco turnout is considerably less than that of the point motor (and, presumably, of regular 00 gauge Peco turnouts). As a consequence, the contact at the base of the switch rod that would change the polarity of the frog can not move a sufficient distance to complete its job (i.e. it remains in contact with one of the polarity strips on the circuit board of the point motor, rather than disconnecting from one and then connecting to the other).

So, either I am doing something very wrong (which is very possible) or these Seep point motors are not suitable for finescale turnouts. As there are a number of finescale modellers on this forum, I would be very interested to hear what point motors they use, and whether or not they have to make any modifications to get them working properly.

Many thanks!

I ordered some Bullhead track last year and yes it was all very drawn out experience. Only just rejoined forum so only just noticed this post 

Looks like that's going to be the case for me too. My order status has changed to 'paid' and I finally received an email last week to say there had been a delay in restocking some items. So, two months later and still waiting to receive anything. I suppose it's to be expected though - the producers of finescale items are probably very small operations.

Longer top hat bushings are available I'm sure. As for the rotating axle boxes....not sure, how deep are they? Could they be sanded thinner?

Bushings! Now that I know what they're actually called, I can search for them - thanks Phil.

Well done on making the move nearer to the proper gauge! Here is a link to a couple of articles in "New Irish Lines" about 21mm gauge diesel locos, including the 121 class. It is well worth subscribing to this magazine if you model Irish railways.

https://www.dropbox.com/s/d86eqxk57ajch81/New Irish Lines Vol. 9 No. 3 - 2021 May.pdf?dl=0

I was rather brutal with my 121 rotating hubs, to get clearance. When shortened I carefully glued them in place so they are now fixed. You have to have very good eyesight to see them rotate at normal viewing distance. I have had no problem with the extending of the wheels to the axle ends, the excess play does not seem to cause any problems.

Thanks for this info Brendan - will definitely check out the articles in New Irish Lines. It did occur to me that the hubs could be trimmed and glued in place, but that seems such a shame when they were designed to rotate. Alas, it might be the only option. Regarding the side-to-side play, it's probably not so pronounced with 21 mm as the wheels are pushed out close to the bogie frame, which (together with the glued hubs) would presumably limit the side-to-side movement? I'll have a look around for longer bushings, as suggested by Phil, but otherwise it might actually be easier to bypass the EM trials and go straight to 21 mm!

Having thought about the pros and cons of 21 mm a bit more, I've decided to have a go at constructing a short length of 21 mm track and a couple of points, just to see what it entails - and I'll convert a 121 to run on it. Before that though, I thought I would ease into the whole conversion experience by first converting the 121 to EM and running it on some Peco EM bullhead track and a couple of kit-built EM points. And so I've arrived at my first bump in the road.......

The attached photo shows a bogie on the 121 with the left wheel set re-gauged to EM (on original axle), while the right wheel set has not yet been re-gauged. What I've noticed is that there is now quite a bit of side-to-side play in the re-gauged wheel set due to the increased space between the wheels and the brass(?) rings that hold the axle in the gear block. This isn't an issue on the 16.5 mm wheel set because the wheels are tighter to the brass rings and this limits the side-to-side movement. Brass rings (whatever they're actually called) with a longer cylinder would seem to be the obvious solution - or some type of spacer that can be put on the axle between the wheel and the brass ring. Does anybody know if such items are readily available? 

Another thing I noticed is that when the wheels are spaced for 21 mm gauge on the original axle, the outside face of the wheel is almost flush with the end of the axle. This leaves no room at the end of the axle for the rotating hubcap to slide on to it. Has anybody found a way around this?

As always, thanks for any input!

Hi folks, 

Have any of you had problems ordering from C & L? I placed an order via their website in mid-September and got confirmation from my bank that the payment went through a couple of days later. However, my order status is still showing as 'awaiting payment/awaiting processing' on the C & L website. Have sent a couple of emails, but no response. My understanding is that C & L is a one-man operation, but still, this seems like an unusually long time. Anybody else had a similar experience?
