Create: Trains on Trains
Have you ever dreamed of creating a train that can transport other trains? This mod is exactly what you need. This is an extension for the Create mod that allows bogeys attached to a carriage but not connected to the rails to move freely with the train without any problems. The main condition is that additional bogeys should not align with the main ones, allowing you to add any number of them to each carriage!
The mod works perfectly with Create: Steam 'n' Rails, enabling you to create transport compositions for carrying trains with bogeys of different sizes.
An important advantage is that the mod works exclusively on the server side, so clients don't need to install it.
