ERR Cruise M in an Atlas Dash 8-40BW

First off, does the locomotive have the Lionel board set or something like TAS?  The CC-M would only apply to the Lionel board set, then you just replace the DCDR, a very easy swap.  In addition, you now can add working ditch lights if you so desire, they're available off the CC-M as an optional output.

Depending on which issue of the Atlas Dash 8, they could be SAW Gen 2 boards.

I don't believe Atlas ever used Lionel Modular boards. It was either a TAS SAW, TAS EOB, or ERR Cruise Commander. Cruise M won't apply in any case. 2 of the 3 already have cruise.

Not true. I have upgraded plenty of ATLAS Diesel that used Lionel Modular Set up with Generic Diesel 4.0 RS.  Even with smoke.  So if it is modular, an easy swap to CCM.  I think I even had one that had Lionel Modular stuff, but they used K-Line Cruise motor driver.  Think it was an F-3 ABA Set,  G

As I said originally, knowing what type of command boards they have is key to advising on the upgrade.

Thanks for advice/info.

I don't have the Dash 8 yet so I don't know which version I'll be working with.

I'd prefer one of the later models with EOB or ERR but they don't come up often so I wanted to check the feasibility of upgrading an earlier model.

I have a TAS EOB board - thank you GRJ!. If the one I find has a SAW board, then hopefully the footprint will be the same. If not, it looks like ERR Cruise Commander is the answer.

The EOB and SAW boards are the same footprint.

Thanks again John.
