Who doesn't love LEGO train sets? I certainly do.

But the modern Power Functions system for motorization, with all its benefits, also came with the need to house a battery box. In passenger train sets in particular, this is a bit of a downside to the system.

My Light Rail design a solves this elegantly by placing the battery box underneath the train, leaving almost the full length of both carriages available for passengers.

Battery box underneath the train, with on/off button and wire to IR sensor accessible behind the shutters.

Removable roof sections - vital for playability.

Seating for up to up to 22 minifigs!

7 studs wide, but still 100% compatible with switches, train stations and platforms.
