What did you do to your trains today?

how about red express coaches?

I could also make red stripes to stick over the green ones when needed so as not to replicate the whole bodies for one different colour. Besides being more accurate in that regard, it's one reason why they don't have green ends like TOMY's. Fully custom shells would only be used for totally different rolling stock (including similar shapes with different colours and detail).

Keep in mind, I have yet to learn how to duplicate Plarail wheels and/or couplings and only have three suitable coaches to use (including the powered ex Annie). Engine front wheels are spoked and don't have the right axles either.
