Steam kits are readily available from dealers even though Midge tells me I have to pre order them if I want one from MTH???
Pete, PS-2 3V boards are the same board, and the code in PS-2 board is Diesel/Steam/Trolley/Articulate. Hence they work in any model, other than those that need a special flash code such as Operating Pantograph, Quill Whistle, small smoke, Coors, etc....
For PS-3 kits you have two issues. First PS-3 steam is a 2 board set, so the flash code and sound files for steam are different then there Diesel counter parts. PS-3 Diesel is a single board.
The actual upgrade kits are board different too. So a PS-3 Diesel board for Diesel kit, and Daughter board for the Steam kit that uses bulbs.
The actual PS-3 diesel board has more light outputs and effects then a PS-2 3V or PS-32 can handle. I am pretty sure PS-32 would operate the lights if you used a PS-3 flash file, but you might not have the desired effect on the engine.
You have to find out what lights function is controlled by the PS-3 code versus the original PS-2. For example ditch lights may be flashing with PS-3 code, but the PS-2 used ditch lights constant on for number boards, etc.... G
