I am just curious why you are doing this? If you put it all on a train in one mission, then... it will be a very long train, and I can't really imagine it looking that good in effect.
The main reason I guess is flexibility. To have it available. Ever since I saw that train in mission 6, I felt that itch, wondering what it would look like when it was actually moving. And the game has a number of train carriages that are actually used ingame, whereas others (like the armored train from the Bonn mission in BCoD) are basically just scenery. I guess I am weird that way to have them available as a real train carriage too . Besides, maybe someone else might use it in a mission they're designing. Isn't it also the reason why you put so much effort into your locomotive?
And perhaps it's true that it will look kinda weird if you make a long train, but I am planning on a mission on a relatively large map where a railway basically cuts the map in two, without giving the player access to that railway. Trains will move in both directions (double track) and I plan to make a few that alternate. The player will be able to move between the two parts of the map, because I plan the railway to cross over a few bridges that the player can move below. While the player is playing the mission, he'll be seeing the trains pass by, of course. I haven't fully decided yet how the map is going to look exactly, let alone the composition of the trains.
Edit: By the way, I do admit that it's a lot more work than I initially expected. I'm using Paint.net to edit the graphics, as it's freeware and has a lot of options and plugins that make it a good alternative to Photoshop. So even if it's a lot more work, it's also a good way to get to better grips with that paint program.
