John asks readers:

“It is important to buy good locomotives. I can vouch for N-Scale Atlas engines, as they run and run and run with just routine maintenance. With the other plastic brands, that can cost as much as Atlas, they run for awhile and then stop, seemingly for no reason. Some of the Walthers RS-2’s run good, and Kato is another good brand. Beyond that, or for cheaper engines, I wouldn’t trust them. In that same vein, has anyone any knowledge of the Kato F-units? They’re supposed to be good for the money, making them the only F-Unit that actually can pull some cars.”
