Yes, those gaps will be filled with cheese slopes. LDD won't allow to place them there, because as I found two cheese slopes facing each other result in 2.6 plates width (a little more than one stud which is 2.5 in plates), but this method of stressing work fine in reality. Most of the cheese slope mosaics use the same dimensions as the "smallest" unit. The upper part of missing yellow cheese slopes will be filled with 1×2×2/3 slope (double), since there is no stud next to driver's cab's window to put it on.

You are right about bogies, they are the weak point of almost all of my models, I prefer to keep them clean since these trains run many real kilometres on shows, I simply don't like when trains derail on parts they lost on previous loop. I wish I could build a framework around bogies which are strong enough to resist forces awaking when bogies enter sharp curves and points.

Ah yeah. I'm not so much into LDD, have started 2 or 3 projects but nothing overly complicated.

Well, that's a valid point for the bogies. No problem to me, as I do like those old style trains of the 9V area most and tend to keep my builds as simple as possible. Though I have other reasons to do that :wink:

Still, your point of lacking bogie details is valid as well, I'll try to design something that fits the model and my expectations about not being so fragile. :)

Hopefully this train will be finished this year or in the first months of 2018.

And for today I'll post about a train I posted about in 2014. Since 8W trains cost a lot (each of my trains are working), it took 3 years to collect parts and finish, today I received the last missing 60 green seat parts.

I'd like to introduce the brick-built version of Hungarian BVmot (nickname: "Samu", 434 series) train, which is a four-car electric motor unit designed for long distance (InterCity) travel in 1994. Only three of them were built due to financial reasons, however they could have been the base of Hungarian InterCity travel. Each train consists of four cars - a 2nd motor car, a 1st class middle car, a 2nd class middle car and a 2nd class driver car.

The motor car and the driver car was challenging, the angular patterns (orange-white, white-blue, blue-yellow) took lot of cheese slopes, but the designed I dreamed about in LDD worked fine in reality. I used quite lot of SNOT around doors - they are built mostly in SNOT, but the positioning and size of train door window required some SOT parts inside the SNOT design.

Other challenge was offered by the middle cars - they have the same length but the 2nd class has 11, the 1st class car has 10 large windows n each side. I used regular blue train windows on 2nd class car, but a different solution was needed for 1st class car - I could not fit a simple tile between each window, because they are 9 plates high and one 1×4 tile put between with SNOT is 10 plates high... So I decided to throw train window and design something having approx. the same size. It resulted in SNOT transparent bricks and plates, with separation of 1×3 SNOT brick. The top of the windows were closed with half-plate thing brackets (9 plate height of normal windows = 1 tile, 7,5 plates height of 3 SNOT studs, 0,5 plates height of bracket.

With this technique every unique window separation could be done in LEGO. Just make sure you push everything strongly together, it is quite hard to fit!

The train is driven with two PF train motors, controlled with PF IR v2 (v1 simply won't make it move on curves). The train is able to work properly on standard track geometry (including points after points and 180 degree turnbacks), however it would look better on custom large radius curves.

In the future I plan to built indoor lights and front/tail lights as well (total of 14 PF leds will be used for this), but because of the cost of LEDs and extension cables it will take couple of months.

The LDD-design is available to be downloaded from this folder:
