Lego Technic Tram in 1:22,5 scale

[princeofgonville]

In May 2020, Paperinik77pk posted this MOC - a tram engine in 1:22.5 scale, made using LEGO Technic, and intended to run on Lego track and G-scale track. The original was a digital design. This autumn, I made one for real.

 

 

Huge thanks to Paperinik77pk for your help. There were a few changes necessary between digital and plastic, notably:

• the original design was too narrow, even for LEGO track. Fortunately there was enough space to widen the chassis, without changing the aesthetics of the bodywork.
• I located the battery box lower down. The original design had the battery box in the roof, which makes the loco rather unstable.
• I made the bodywork easily removable - just held on with axle-pins into Technic beams.
• Mine has gearing to slow the loco down.
• It runs great on LEGO track and is pretty good on G-scale track. The profile of wheels is too coarse to run on SM32 track.

Thanks again to Paperinik77pk for your help.

Great work, thanks for giving it a try, and for correcting those design flaws!

I love to see it going around!!! 

Nice little wagons too!!!

@princeofgonville Do you need to modify the wheelbase between G & L gauge?

@M_slug357 yes you need to as g gauge rails are further apart than l gauge ones. see here:
