i have double tracks and when im running two engines why does one goes slower than the other. im using a mrc tech 4 280 both engines are about a year old
thanks grumpygramps75
There are too many variables, even between two supposedly identical pieces of machinery, to expect them to perform identically. Generally, if the units are the same, they will run close enough to the same speed to allow them to run coupled together.
If identical speeds are important to you, you would be better off using DCC and tuning the receivers to get the locos to run at exactly the same speed.
What are the variables? Friction in the bearings, smoothness of the matching surfaces of the gears, play in the gear mesh, end play in the drive shafts. And so forth.
