Ah I wouldn't overcomplicate it. I'd stick with something like this: https://www.ebay.de/itm/272322746439 That's a Bluetooth receiver with an integrated 3W stereo amp. That's at least as powerful as a Loksound V5, which is 3W but I think it's mono so only half the power.

I'm not sure that particular module can drive a speaker directly. There's no mention if how many Watts it can drive which leads me to believe it's just a pre-amp. I think you can buy similar receivers with a class D amp incorporated into the board though and probably for the same sort of price. Fascinating possibilities alright.

I think pin 12 on a 21MTC decoder will be Vcc at +5v. The function outputs actually get pulled to ground to make them work as these decoders use a common positive at track voltage (pin 8).

Sean the MM sound files in the ESU site aren't the best anyway. There are hifi V5 files covering those engines (12 cylinder 645 Turbo file for the 071 and 12 cylinder 710 turbo for the 201). I don't believe the MM files were actually recorded from Irish locos or anything like that. The 121 one definitely wasn't IMO. They are US recordings but like you they are more than adequate for me and they are good quality recordings by ESU too. But yeah you can convert the files to v5 format. I took the above v5 prime mover sounds but the horns from the v4 projects and saved them as by and it all works so I guess the decoder application would also be able to decode them. Thanks for the links. I'm good with German so I can ask in there though it seems the developer is not a German speaker. He posts in English I think. Impressive progress for such a young project anyway. Hint: if you see NT in the ESU filename it means non-turbo. These are the ones you'll want for the small GMs.

Very interesting Sean. I had been mulling over a homebrew implementation of the above idea (using Rocrail to run an external sound player like VLC) to save money on sound decoders but it seems the tech has already overtaken me and it is possible inside Rocrail and amazingly using esu files directly? I will certainly be investigating this route before I spend any more money on sound decoders. Personally I don't think I want my locos making noise everywhere on the layout. It would just be a cacophony of sound like that. I always wanted sound at "points of interest" and fixed speakers at stations etc. we're something I was going to install regardless for other sounds like station announcements that match the actual train in question. Do you have any useful links to share? Edit: Ah I googled a bit and it seems the decoder application is external and relies on windows dlls from the Lokprogrammer software. Is that the application you're using Sean? Could still be an option for me but not sure how it would work with the system I have in mind (not z21 based but maybe I can use the same passthrough/emulation method you did with your dcc++ hardware). Definitely worth spending some time on I think.

How long did it take to sell out the A class? A few months max, many liveries sold out almost instantly. How long did it take to sell out the baby GMs? Much much longer because there were far fewer people in the market. PM created that market for high fidelity Irish RTR and the beginning was with the baby GMs really. Nobody knew then that there would be much of anything to haul behind them so people were largely buying them on spec for the novelty value presumably, never expecting that an industry would follow. That's not the case any more. The would be customer now already has the stock to haul and knows more is coming down the line. But I am not arguing for a release of the baby GM by anybody as it's not my place and they would be mad to listen to me anyway. I am happy to anticipate the other things that might be released over the coming years. Hunslets are at least as viable as "obscure" mk2b NIR diner cars and whatnot Nothing seems to be off the table. The magnesite wagons would appear non-viable too. Only ran for a little over a decade and only in the south of the country and only really with 2 liveries I believe. But here we are and they are coming so they are viable So I have learned not to try to second guess IRM. A fool's errand if ever there was one. I'm happy to sit back and be amazed!

I'd say the baby GMs would already be financially viable now given the seemingly rapid expansion of the market, but there are other fish to fry first probably.

I think he said it was running perfectly on analogue. Don't think he mentioned DCC at all.

This. A huge amount of pride felt by me too and I have nothing whatsoever to do with IRM apart from being a very satisfied customer but one can't help but have a sense of pride in an Irish firm taking the modelling world by storm like this. There is literally nothing stopping you from being the market leaders. The foundations have certainly been laid.

I had to play around a fair bit in Lokprogrammer to get the desired result on the 121s so I could lash a pair up nose to nose and have them behave as a single unit for the purposes of lighting (primarily having no nose lights on at all when lashed up but also ensuring I could hit a given F button to toggle "light power"/"hauling something" so that I could kill the red marker lights when hauling a train.

Hi Sean Nice thread. You could also have a play with RocRail in place of JMRI. It's the "European JMRI" if you will. I haven't used JMRI so can't compare them. Maybe the architecture is similar. RocRail is client/server based. The server connects via USB or whatever to the DCC hardware (in your case the Arduino+shield). My RocRail server runs on a Raspberry Pi Model B (my DCC hardware is a fairly old DIY openDCC controller), so very little computing power. You can then use your laptop or desktop running the client software in edit mode to edit the configuration. You could use the same application in "run" mode to control/monitor the layout BUT as it's client/server based you can just as easily install the android app or webapp to control it. You can have as many clients as you like. I'm not sure if RoCRail supports the Arduino protocol but Rob (the principal developer) is a fan of all things open source so I wouldn't be surprised.

Love it.

On the other hand, N gauge models are "small" so resin printing with its higher resolution could be a viable option?

Good call on N gauge actually. Far less likely to see any N gauge RTR in the near future, if at all.

I'm a big fan of the 3d printing. Definitely going to get into it as time permits but I would keep my powder dry on anything that just might be manufactured RTR and I believe we are on the cusp of a whole new era in availability of older Irish RTR rolling stock from IRM. The guys are young and have proven themselves already and if we look at Accurascale we see a readiness to go way back in time. I intend to use 3d to create stuff that I think will unlikely ever be released RTR, mostly track work. I hope that IRM can relieve me of the task of building a lot of kits and so on and I can spend my time on the layout and details that will never be available to buy. I have been "burned" once in that I bought a a dozen Lima mk2b's but I will probably never convert them now as it's extremely likely that IRM will produce the mk2b IR/IE stock given the NIR announcement (which I had also planned to do). This saves literally months of modelling time to work on something else...and there's always going to be something else.

I'm a real mid 90's fan but I picked up the A's that would have been around at the end of steam as I am minded to someday run a small subset of stuff from that era as it is so different to the 90's. I can only reiterate Fran's comments...if you are even remotely likely to do similar, pick the available A's up now to avoid paying through the nose later. You'll always get your money back if you decide later not to pursue the era in question and sell on. You may even find you can swap for something really elusive as somebody else makes the opposite decision and so on.

Any chance of the old lovely garish YM LINE 40' ones @Arran ? They were regulars on Irish trains in the 90s. Sometimes several in a train. The plain green Consent Leasing also a big gap I'd say. Boring enough container but very prototypical in a Bell Lines block train. Also be nice to see the 20' Bell reefers and tanks make a reappearance some time

I remember the Olympians replacing the KDs. Man that was an improvement, no longer half suffocating to death from the diesel fumes in the lower saloon.

Notwithstanding the excellent track work, fitting of the front skirt also contributes hugely to the overall impression. I have already planned in my head how I will allow my locos to be turned at each end of my layout so that I can achieve the same look, with just the "rear" Kadee coupling fitted. This is really inspiring stuff John! Love it.

Wonder does it retain the black and white bilingual warnings and notices.

Cast Cuts Costs.....unless you can't stop buying them lol.

Yeah that video is great. The green containers scattered among the Bell unit trains were Consent Leasing. I guess leased from them by Bell due to a shortage of their own boxes at the time.

Extremely useful for many I would have thought JB, and as this era becomes more popular, even more useful. Many thanks for taking the time to write that up.

It's a great way to add significant variety and colour to a layout. I'm looking forward to the 47' and 62' flats some day to justify buying even more containers lol.

I think the P&O, LYS-LINE, Evergreen and Nedlloyd ones are definitely ok on a 1995 layout, which is what I'm aiming for. I am pretty sure I've seen all of these in photos or videos of Irish Rail liners from the period too.
