Hi all,

I have, for the past several weeks, been in the process of trying add a longer bridge and pit to an Atlas turntable. I have been having problems with the pit and bridge. I messed up the cutting of the pit and it is not exactly circular and the central pivot that the bridge rotates on is not exactly centered, so the bridge is liable to bind as it rotates. I have done my best to fill in the pit to get it circular, but the bridge is still an issue.

Time to turn my research to controlling the two turntables on my layout.

One question first. Will a DCC reversing module be needed on a turntable?

I acquired two HO locos (streamliners with dummies attached) from a garage sale for cheap.  Both run on my standard DC layout - but in reverse only.  Can't get them to run forwards even by switching track polarity.  Found these circuit boards inside both.  Looks like an early form of DCC but the blue trimmer device is making me question this.

Any idea what these are?

Good morning.

I likely have missed it despite my spending all too many hours on Amazon and MRH searching for the desired T- Tap connectors.

While 3M and Micro Mark (3 M products) do offer T Tap IDCs in the desired wire format, I have not found any IDCs of the same size in multiple colors.  To clarify, I would like to follow tradition and use Black and Red for wiring but I have not been successful in this regard.  I would accept other colors provided they are in the same wire size, i.e., Red/Blue; Yellow/Green, etc.

Have I missed them?
