As Rick mentioned, lubing the intermediate shaft may not hurt but will it really help? The picture John showed in the initial post shows plenty of grease on the gears, yet the gears are still chewed down.
At the risk of beating this horse to death, does anyone agree that it'd be a good practice to either assuming one wants their locomotive to run a hundred hours or more: (1) not load these engines with too many cars, or (2) create lashups to thus distribute the pulling load. To me, this is logical as it means less load on gears = less wear, but what do I know.
