   THANK YOU !!

Harry, If you're patient, I'll assist you next Sunday night.

If the "old Lionel Hudson" has an AC motor - as they did - and you have a new Williams

scale Hudson - which has a DC motor - these boards would not be transferable (w/o a

rectifier, anyway).

These boards have "TAS" in at least one spot - this is "Train America Studios" which is

defunct.

Not to spend your money, but the Williams scale Hudson has a really terrible gear ratio,

and would benefit -greatly- from an ERR Cruise Commander system.

I know this from first-hand, did-it-myself experience. Good instructions; easy to do;

great plastic coal load on that loco for your antenna mount.

That's a old Railsounds 2.5 board as well.  May not be worth putting in.

I see no RS 2.5 boards, what are you looking at?

The RS board in the middle of the first picture,  with additional closeups.  Unfortunately, the pcb1060 cross to a RS 4.0 part in lionels data base, but the chip is a RS25 generic steam chip.  The power supply is on the top board with the speaker.

Folks are correct though, the MB with the R2LC does have triacs on the motor control section without the Rectifier, so this looks like it is for an AC motor.  G

Actually, that's a RS4 board, and that steam chip is the exact same chip that came with an ERR RailSounds Commander RS4 board that I've installed.  Hard to believe ERR was shipping RS 2.5 chips in RS4 boards.

I do know that you can use RS 2.5 chips in the 4.0 boards, I've done that.  In any case, the contention that this is a RS 2.5 board is false.

Here's the earlier RS board, it's a one piece unit.  This is a spare that I keep when one croaks.

John You are correct about it not being 2.5 platform, but actually and we are starting to split hairs it could be a RS 3.0.  The RS25 chip is in many of the early Lionel RS3.0 boards.  The generic steam for that part number shows as RS4.0 but Lionel shows it with the RS27 chip; not RS25.  G

I'm not sure about the chip vintage, but the one illustrated has decent (not great I agree) steam sounds, and would certainly work out fine.   I based my answer on the fact that I got one with the exact same markings with a RailSounds Commander direct from ERR.  I don't know how to actually tell what vintage the chips are, there is no index of markings to the RS version that I'm aware of.
