You did a nice work. I I like mainly all your train you did.
I'm just wondering if you can add old French train too ?
I put some link for you to see how it's look like.

1) Model n°1 with 2 engines as Z 1500 : https://fr.wikipedia.org/wiki/Z_1500

2) Modèle n°2 with 2 engines as Z 5100 : https://fr.wikipedia.org/wiki/Z_5100

For you kind information, during the time there is less passengers, it was only 1 engine in front and 1 engine on the back. So only 2 cars.

But, when it was very crowed, it was model n°2 by 2. So, total 4 cars.

This train was on small ligne like this and then on the big main line as line C in Paris (France)
called "RER C", it was 1 engine in front and in back plus 2 passengers cars between them.
So, total 4 cars (engine + passenger+ passenger + engine).
When it was crowed, is was put un double . Total 8 cars.

If you can do it for the game, thanks in advance.

Very nice ! It is very similar to the trains in real life, SARA is the name of the train which deserves my city ;)
