HLM - 0m SJ K22 loco
This article was published Nov 04, 2017.

Freelance NG version of the swedish state railways K22 loco type.
Intended for 0m (1/45 on 22.4mm) track, but "should" work for both 0n3 and 0n30, even if I doubt it, it is rather big for those gauges.
Plenty of space in-under to fit most loco chassis of your choice.
Kadee 0 scale couplers recommended.
