RailKing 2-8-2 PS23 Upgrade

Ideally you'd want to put a PS32 board with 5V connectors where the old PS2 5V board was. Can't say if it would be best to move the PS32 board to the tender and rewire the locomotive. I've never had one of those locomotives in my hand. Hopefully one of the techs who posts here will have worked on one and can guide you in the correct direction.

Hi Lou,

I totally agree with your comments. The problem is the new board is about 3/8" wider than the old, not sure if placing it into the engine is even possible.

Can you mount the board on it's side and still have clearance to put the shell on?

A preliminary check indicates clearance for wire connectors will be an issue with mounting the board on its side. Crazy tight.

Update:  I decided to replace the RailKing 5v board with one from a Premier W1 electric.  Big & roomy in the W1, the RailKing was way too much work so I am pushing that effort off to another day!  Next step is to download the sound file to the replacement board.

I have the same locomotive and when I opened it up and saw that I cringed. I plan on upgrading to PS2 the kit has been ordered. I am thinking about relocating the entire board assembly into the tender I don’t think the RE wiring will be to difficult to do but I will see and learn.

hi for the engines that have the 5 volt board inside the engine , usually the ps 3/2 board won' t fit so all you have to do is gut all the wire harness's boards etc from the engine speaker battery everything . then mount your ps 3/2 board inside the tender drilling whole to mount board install wiring harness new 4 ohm speaker and mount tach board harness on flywheel motor connect wires to smoke unit motors headlight load flash code for your engine and download file from mth websight  . takes time but it is not hard just time consuming! make sure you do not  pinch any wires in train body and or frame or tender where board is mounted!

Agreed-the tender is the only option, but it is so short I was thinking about how to hang the board over the speaker and deal with the heat sink & shell clearance.

Please post pictures of how you tackle this, as my fix will only last as long as the 5v board I installed  😕

This is a berk I did along time ago, they ar PITA with center speakers.  I also have installed PS-32 in RK engines, but not all will work, but many do you just have to watch wire management and custom make a heatsink and mounting structure.  G
