"Houston, We have a problem"
We had family visiting for most of the weekend, so I didn't get a lot done on layout - until they left for the airport on Monday morning. I spent the first part of Monday afternoon getting the remaining feeders connected to the buss wires. Then I tweaked a troublesome turnout on the south end of Richmond (just beyond the bridge scene). Once I got the passenger cars through it without any issues I dug out the Division Point 2-10-4s and one of my Overland 4-8-2s.
The 2-10-4 made it through the mainline route of the switch - the diverging route traveling northbound direction was no joy - that wasn't a surprise and is something I can handle with a timetable special instruction (there's no reason for a 2-10-4 to be on that siding anyway).
Then I got out the first 4-8-2 - it ran back and forth just fine, I was thrilled. Then, the engine stopped. I mean it just froze. I immediately suspected a wiring issue - after all I was testing the wiring. Then I figured perhaps it was a track issue - no problem, the engine was on the rails. Then I noticed the side rods were a funny shape - the main rod looked like a mountain range - going up and down. That can't be right. Apparently the long screw holding the valve gear assembly into the third driver had loosened to the point where it slipped out of the driver on one side - throwing everything out of whack.
I put the engine back in the box, and put the other 4-8-2 on the track - checking it to be sure it was in good shape. It ran back and forth even better until it started stuttering - I shut it off right away and examined it closely. Believe it or not, this engine had the EXACT SAME issue - loosing it's siderod screw after a few runs back and forth.
So now I have two engines that are down hard until I have enough time to really work through the issue. I've never been much of a locomotive mechanic - looks like that's about to change.
I'm so mad I could spit.
