That's actually really useful.

Me neither! Fig. 1.2 in the "Track" book shows BH rail on concrete sleepers on the Shrewsbury to Aberystwyth line in 2010. So it was definitely used on the mainline in GB. I think you are right though that "simple" FB rail was more popular in Ireland, which is worth noting. I think I'll try to model a good mix of the types. I may even model the CWR on Cork line as in retrospect, the track will be difficult to see and modelling it is easier. The pandrol clips are so low profile that a little drop of solder is good enough! For BH you really need the chairs for it to look right.

BH was definitely used on mainlines in the UK and Ireland before the transition to FB began. I read that in my recently acquired "Track" book by the 2mm Scale Association. I am pretty sure you can even still find it on the mainline on concrete sleepers, but only lightly used lines.

I wonder was anything like Fig. 107 ever built in Ireland. I think they'd only resort to such things if space was very tight. Note the joggled (kinked) stock rails for the second set of facing switch rails, whereas the first set would appear to be "undercut".

I've done a bit of research on these things lately so I'll just add a bit more background. The select is physically identical to the v4 but it is hobbled by ESU at the factory to make it less capable than a real v4 by flashing a different firmware. This can't be overwritten by a Lokprogrammer. Apparently this is purely a business decision because ESU wanted to compete in the US market where these sorts of limited decoders dominate. Rather than building a new decoder, ESU just hobbled their existing one. The hardware cost difference is probably negligible. The development costs are sunk anyway. If they didn't do this, nobody would buy the v4 at full price. Everyone would buy cheaper "selects" and use those. It is interesting to hear that the v5/v5(US) will have "less hobbling" than the v4/select. That would appear to be the route to take if one can only source ESU decoders in the US as v4 files should work

I particularly like such posts. You learn from your mistakes as they say but it's even better if you can learn from someone else's. I don't even own an air brush but when I do I'll have registered this little bit of information at the back of my mind as something I need to be aware of.

What about the EMD 12-710G3A LATE EXH T? ESU returns this with a reference to the 201 if you search ESU for "Irish".

Thx for the clarification. In that case (at least in my case with 6 121s on order) it probably makes sense to maybe get one MM decoder and try it for size. If I'm going to end up replacing the whole sound file for better driving features then I may as well program cheaper blank ESU decoders and spend the difference on more stock. If you do reprogram your 121s where would you get the ancillary sounds (horn especially)?

What exactly do you mean here? Would you be left with anything of the MM sound file following this reprogramming?

The ESU files for the 071 and 201 are the same as those preloaded on the MM branded decoders, are they not? For the babies there never was an original MM decoder at all AFAIK so we're really only talking about "original part or spurious" for the A Class and the 121 if I'm not mistaken with the above assumption. I see an argument in both those cases for taking a custom (proprietary) made solution, especially for the A as it has been confirmed that the advanced driving features will be included. For this reason I'll probably opt for the IRM chips but for the 121 I'm still undecided.

Is there a viable "ESU only" approach to the 121s? The prime mover should be no problem from a US donor project but what about the ancillary sounds? Can one easily swap out say the horn sounds?

Ok good to know. Thx.

Lol I was just about to ask as I have 4 IR A classes on pre-order. Will these sound files be available for download on the ESU site or will they be proprietary and only available by purchasing a pre-programmed decoder from you guys?

That would be a shame indeed and if the rumour mill is correct and MM retain exclusive ownership (unlike the situation with the 071 & 201) then the modification using the Lokprogrammer based on US throttle controls would sadly not be an option.

Would it not be the other way around? Beautiful work that can really be considered art.

Cheers for the clarification Noel. I picked up a used Lokprogrammer on eBay already and I can get used Loksound V4 units for €80 so that's the direction I'm heading in for those two classes as I will have quite a good few locos to equip. I can live with "good but not the best" given the significant savings across a fleet of what will be around 30 or 40 locos in the end. From my understanding the Lokprogrammer allows you to reformat any v4 project to v5 so even if I can no longer get the v4s I should have a fallback.

What is the difference between a "genuine" MM decoder for the 201 and 071 and a self programmed Loksound V4 using the ESU projects which are available to download for those two models specifically? Is there any difference? From reading the ESU page it sounds (haha) as if these are the projects that were used by MM (it says OEM) themselves.

It would make a great feature if you could recreate slip coaches in model form.

Lovely work Noel.

Ken, thanks for your explanation. It is certainly worth bearing in mind for certain sections of my layout and doubtless for others. For my layout I will almost certainly be starting with soldering directly to copper clad, simply because the first part of the layout to receive track will be either the difficult to see eye level (but set back from the viewer tight to the wall) section or the hidden staging stuff which can look as rough as a badger's behind but actually needs to be the most reliable track of all as access later will not be the easiest. I anticipate a long testing phase before the scenic layer can be begun. All my stock will need converting and at least a couple of examples of each type of stock need to "be cleared" over the hidden areas before they are built over.

If you have any and are prepared to part with them (postage or collection to/in Dublin or Berlin areas) please drop me a line with your asking price. Thx, Phil.

I will keep an eye out for it but it's not easy to find.What's the difference between that one and the pragmatic Guide to building, wiring and laying PCB track by the same author?

Yeah my bank balance knows how expensive stocking the layout is Anyway it's a nice complaint to have. It wasn't that long ago we had no real RTR options to blow money on! Interesting idea with the regauge for the fiddle yard. Is that going to work out cheaper/faster? Don't I still need to solder copper sleepers every few inches anyway?

Unfortunately money is an issue and as my layout will have lots of track and many dozens of points, saving money by by building those myself is financially attractive, even if it's much slower. I can use the money saved on great quality kits and RTR items that I could not realistically manufacture myself in the number of years I have left on this green earth! I will make the off scene stuff and much of the eye level mainline track panels in jigs to speed up production and build the waist height station trackwork in situ most likely. But I'll have to get a feel for it. Seems it's a matter of personal taste.

Anyone interested in a swap for an unopened MM1508 in the Dublin area? I'm in Germany but the coach is at the home place in Newcastle still in the parcel it arrived in. You could combine handover with a little visit to Marks Models around the corner I'd take a mint standard class Craven (either livery) or a mkIId anything except restaurant cars in tippex livery. If interested please PM me.
