    I have drawn up and 3D printed the auto gear that goes under the driving end of autocoaches, I think it really makes a difference, I spent last week measuring up the autocoaches at Didcot.

    This has been designed to fit the Bachmann model but should also be ok for the Airfix/Hornby model. Cost is £7.50 for the 4mm version, I also do a 7mm version price to be worked out yet. If you would like one please email me direct on

    I am drawing up the autogear for the trailing end too as this is different.

    Hi David,

    Will you be doing the auto gear for the trailing end in 7mm as well?

    Yes I will be doing all the parts driving and luggage end plus loco bits in all scales from 4mm upwards due to the fineness of some bits I don’t think 2mm will print. I have even been asked for gauge 1
