A basic train which would run on light rail or rural national rail systems using battery power, ideally with 2 cab cars on Hornby 00 Gauge train bases of your choice, aswell as some passenger cars. I will add a modified version soon, with a Jacobs bogie style capable system. ENSURE your printer can print up to 300x300x300mm, and the width of the cars should be at least 38mm. If it is, and is scaled evenly, the whole train will be a good size for Hornby running, or at least better than my last train.
