Gauge 1 Marklin BR78 2-rail electric 4-6-4 Tank engine
Here we have a Marklin BR78 German Tank Engine, this is still setup as a 2-rail pickup loco and can be run on Ac or DC current.
It is in perfect working order and in my mind ripe for a R/C convertion. Maybe with a string of freight wagons or coaches behind it.
Condition wise the loco is like new, though the box is a bit tatty.
