I have a relatively new Bachmann 37 and it has been running light engine for a while to run it in. it is still making a faint grinding / buzzing noise in the transmission despite it running smoothly visually. by contrast my Bachmann 20 has run for hours and still sound and runs smooth. I have never opened up one of these locos and was wondering if this is a common problem where a certain part of the motor or drivetrain just needs some lube
