Your 4 wide beats a lot of the 6 wide out there! I can only imagine what you would be capable of building in 8 wide (beyond perhaps having to take out a second mortgage on your home to pay for it all, grin).

Well, I figure that using LDD is free so I'm not bankrupt yet. :grin:

However, I have decided to dip a toe into the world of "proper" LEGO trains by knocking up this 8-wide rendering of an SNCB/NMBS AM08 Desiro passenger train. These EMU trains can be seen operating throughout Belgium on local and intercity services and are among the most modern passenger trains used by this operator.

So far I've only got as far as designing the train in LDD but, unlike my earlier Desiro UK, this one is both buildable and intended to be powered.

I wanted to make this model to scale, which is why it looks excessively long by LEGO train standards. I took the formula of 1 stud = 15 inches to arrive at a total length of 210 studs. I appreciate that this might make it difficult to operate on anything other than the widest of ME Models radii, but I'm taking looks over operation as my starting point. It would be possible to reduce the length somewhat if necessary, but I'm hoping to avoid that if at all possible.

There is a gap between the black and dark bley arches at present because no brick exists that will fill that gap, or at least not on the LDD palette. The intention is to use a length of light bley pneumatic hose instead.

Thoughts, comments and reactions are welcomed, especially as this will be my first venture into full-size LEGO train construction.

While I don't know much about modern EMU trains, this (virtual) MOC is very impressive! I can only assent to LT12V's words.
It's also really nice to see a train model in full scale length!
:thumbup::thumbup:

As for the gap between the front arches: Isn't the diameter of the pneumatic hose too small to fill the place?
I have to admit that I can't think of a better solution at the moment, though.

Thanks guys. I'm glad you're liking it too. :classic:

I fear you may be right about the diameter of the hose, especially as there is a void inside the larger outer arch. I did wonder about threading Technic half bushes onto a flexible axle cut to length, but I guess I shall just have to experiment. It does strike me as slightly weird that there appears to be one size of arch missing from the sequence. Maybe someone somewhere has come up with a custom part to fill the void, if you'll forgive the pun.

Great job. Beautiful train turned out. Personally, I have no idea how to improve the train. He's already great. But you can also build a train six broad. Here's the Russian version of Siemens Desiro RUS from the builder of the pavlo.

According to my experiences with long cars, a train car with length of 64 studs can be operated easily on standard track geometry. You wrote that your train ended up with 210 studs in total, which is 70 studs for each car, I suppose to have 64 studs for middle car as long as end cars shouldn't be connected to other locomotives or cars on their ends with driver cabs. 

I also recommend to run it with at least two train motors (PF) and with PF IR receiver V2, with V1 it will slow down or even stop on sharp curves thanks to the high current consumption of PF train motors (...one motor needs less current, but won't run this train).

Alltogether it is a really nice design, however I dislike the side of driver's cab - the black curved slope and the grey arch next to each other don't match the real thing, maybe with differently angled SNOT-slopes you can achieve closer match to the original train. You may also consider to drop the usage of old-fashioned black train windows - they are quite expensive and don't match the modern-looking train, consider to use trans-black panels instead.

@Ashi Valkoinen Thanks for the advice and pointers. I've provided one train motor at one end but it wouldn't be difficult to add a second one at the other end too to help it around. I was intending to use an SBrick that I've hidden inside the roof rather than an IR receiver which I think will deliver sufficient grunt. I didn't want to use window panels because, although slender, the Desiro ML does have black window frames, but I do take your point about the cost and availability of the parts I've used in the LDD file and will probably substitute them for something else.

It may not appear so from the prototype photo I posted for comparison, but the front profile of the Desiro ML is curved rather than slanted and the SNCB/NMBS livery follows those curves up to the roof. There is meant to be a narrow pale grey strip between the black panel surrounding the cab window and the darker grey stripe that runs up to the roof, which is the part that's missing so far. I'm not very experienced with SNOT techniques so I might not be heading in the direction you were thinking, but I have revised the design around the cab slightly to deal with the gap. Not sure if this is any better.
