This is everything you need to run your very own narrow gauge railroad! Most of these trains are based on the 1/87th scale HOe gauge model trains from the likes of Roco and Tomytec. Most of them can go anywhere in the world, but the bigger ones are based on Japanese prototypes.

Notes:
Railcars and Carts do not have drivers' seats, so you will need to spawn them with a locomotive. I had an issue where the engine would stall when connecting it to an unpowered railcar.
I recommend only pulling the small carts using the Diesel Tractors and other really small locos.
Railcars with trucks don't reverse around turns very well.
Use tracks in godmode.
The couplers are all at the same height for inter-compatibility.
Carts do not have hand or train brakes.
If you need more help to get up a hill, add a calf on the end. Calfs have their own engine and braking systems, controlled by the locomotive!
Cabooses have brakes on them. If you need to go a long distance or need to be able to stop fast, a caboose could help with your cart train.

Right now, I only have trains and track in the collection, but there will be scenery, buildings, and of course, more trains later on.
