LGB just recently announced their 2021 new products, and new track cleaning locos are there: 21671, and 21672 for UP fans.
I have to say I'm interested, even though I don't have a layout yet
(And if I had, it would be covered with 40-70 cm of snow at the very moment! How many Stainzes would be needed to push the snow plow that could handle that...?)
I presume the new models drive very much like the previous 21670. How practical is a track cleaning loco without using the cleaning motor, I mean, is it suitable for also used as a normal loco when not cleaning? It has the couplers sure, but from the pictures it looks like the cleaning wheels are down on the tracks all the time.
