@boomer0622 posted:Don’t forget to lube the wheels on the cars as well. I have found that older cars that have been setting for a number of years can have a lot of drag . Sometimes you will also need to clean the crud off the wheels.
Just to clarify for a new user...
"Lube the wheels" refers to the axles and bearings - don't get oil anywhere near the surface that makes contact with the rails. And don't get oil on the rails for any reason.
