This train is perfect as a toy for children or for collectors. It has been designed for print-in-place printing and does not need supports. It consists of the locomotive, the passenger car and a cargo car. You can repeat the cars you want and connect them with the coupler.

No supports needed, make sure you have good adhesion to the print bed, if necessary use an additive, in my case I use a bit of strong hold hairspray.
