how old

Well I made a few laps with both locos and after a few laps each they started to make noise like they were dry so I will get some oil and contact lube in Chattanooga this weekend and did I read that somebody files the edges of the rail just a tad because I can see where it would help, forward was no problem but reverse would seem to hit a bump sorta and with the finger rub test I could barley feel a little bump that lite filing would fix

I read on here that spectrum kinds over lubes them during manufacturing ...is this the case or should they be lubed before break in , also they seem kinda slow compared to some videos of other ho scale trains...will they get any faster after break in, or, will dcc make them any faster
