Looking for non-destructive way of opening the headlight case to replace the bulb on the 2-6-0, or a link to a video demo that is current and clear. Mine also seems to be mounted via melted lugs to the brass support frame in a way that makes it non-openable? Goal is a warm-white LED as part of my DCC conversion. Thanks.

Any information about when On30 arch bar trucks 29901 will be back in stock?

Am looking for a "bumble bee" Durango and Silverton 4-6-0 and have found locos with different numbers. I read one post that it was reissued and upgraded with better gears, metal side rods, etc.  True? What is the difference between 177 and 179? I want the most recent.

Can someone confirm that 31mm wheels sets part 92421 are the blackened ones? Was the number changed from the original silver and black plastic center ones? The pictures most sellers post for 92421 do not look like blackened wheel sets to me. Thanks.

My 2-8-0 has seemingly a binding problem as it wants to stall out on Aristo 5'D curves when running a medium slow speed. Need to punch up the power to get it going. Engine is new, I think I have the tender drawbar at the right length, and lubed per specs. I know this is probably the minimum radius track to use, but reviews said it was OK. So will this maybe loosen up with time or do I have to tweak something?     

What are the two extra blue wires in the bunker of the 82498 for?
