I bought one of these new in the late 1980s. It hasn't had a lot of running over the years, but I notice that the bodywork beneath the rear of the loco gets very hot. This occurs on both dc and dcc operation.
Drawings of this loco from the internet dated 1999 show the motor to be located under the cab floor, with a worm on the motor shaft driving a gear on the rear axle. However, the leaflet with the loco refers to a gear box needing lubrication. This isn't shown on the 1999 drawings.
The motor appears to be getting hot as I can't see any route for cooling air to circulate around it. It sits within a sealed box of the loco frames at the sides, the cab floor above and another section of bodywork underneath.

Has anyone else experienced this problem? Is there a solution?

Thank you very much for any suggestions.
 
The motor on these locos gets very hot. I had one running all day at a show & it melted the chassis. The only solution is to not run them continuously. At a show I now use at least 2 locos & swap them at intervals.
 
Your suggestion is very sensible. I think that holes would help, but I am reluctant to start modifying an otherwise pristine LGB loco.
 
Thanks Fred2179G for your comment. Having noticed the problem, I tend now to run it for only short periods. I can live with this restriction, but I'm surprised that LGB didn't design some cooling flow through the bodywork.
 
Yes, I have noticed that this loco runs hot. As I use mine mainly for shunting/switching (on a Ginglenook puzzle layout), it does have time to cool down.
 
Hello Gavin, and thank you for your comment. I'm sorry that I have been so slow to pick it up. I'm re-assured that the problem isn't unique to my loco.

We visited New Zealand in 2011. My wife's father had been there at the time of the Napier earthquake, on a tree-planting scheme. We visited a Kauri museum, where the staff very kindly tried to locate his name in their records. I remember Wellington for a floating crane in the docks, the cable car to get up to the Botanical gardens, and the steep hills from houses to garages that required some form of small electric lifts. Our coach tour of NZ was memorable in so many ways. Happy times!

Regards

Malcolm

That was the Wellington one, very next frame, and on the same date was this 'real' Cable Car in San Francisco.

Thank you very much. I liked the photos, especially the view over Wellington. I was surprised to see that the ferry across to Picton was a renamed ship from the Dover-Calais route between England and France. Luckily we had a smooth crossing and enjoyed the sea.

Malcolm.
 
Yes, i have several frr engines, as well as chloes and olomanos. New and old designs.
All run warm indeed.
I cant recall the motor brand, on the old, mabuchi? Not buehler. (The redesigned marklin frr locomotives use a different brand motor.)
I too limit running to about 15-20 minutes, no more than 2-3 frr cars. Runs warm even light.
I think the heat must be inherent to the motor, as other enclosed and non vented motors do fine.
Perhaps a heat sink…which would likely be more trouble than worth…

What makes a motor run hot?
