Any issues with running a PS2 steam engine without the tender (and the PS-2 plug / cable connected)? The reason for asking is for troubleshooting. I was running an Imperial Mikado last night I picked up gently used at a train show and it developed a noticeable squeaking. I ended up running it without the engine sounds and determined it was simply in need of a little more oil on the side rods - I had Very lightly oiled the rods and linkages a few days ago before running but it was apparently not quite enough. While trying to determine what was causing the squeak it would have been helpful to run just the engine without the tender.
