Hello all--
This is my first post on Eurobricks, and I'm a newcomer to the world of Lego trains (for the last 30 years, I've focused on collecting G-Scale LGB trains). I'm building a collection of 9v and 12v trains, and lately I've been drawn to the older 12v sets and parts, primarily because of the control options available with the 12v line.
I've noticed that many of my 12v motors, while they are in good condition, need a little help getting started after they've been sitting awhile (overnight, etc.). I need to push the engines to get the motors moving. After about 3 minutes on the track, they run fine, but I'm wondering if any maintenance (greasing, etc.) is needed (or even possible) with the older 12v motors. What's the general opinion about this? I know my LGB motors need a little fresh greade every 10 years or so, but looking at the 12v Lego motors, it's not even clear they can (or should) be disassembled for maintenance.
Any help or guidance would be much appreciated, thank you all!
