Alright, here are the plans
In the next version, a new add-on, Script_Trains, will be released. This will make trains compatible, and would control all trains, instead Vehicle_Train_Box controlling itself.
The point of doing that is so train vehicles(if any in the future) will have the least amount of code while Script_Trains handles everything.
The expected release date for the script is
July 31 anytime this summer.
Randy has also helped with a now-working /aligntrain [direction] command.
New GUI
Now, we want to work on a new train. Stratofortress said he "bailed" so I need to find a new person to model. Anyone?
