orig title: help: Legacy dash 9 started crawling

I have a CNW legacy Dash 9. It has been running fine for several years. Yesterday I had my neighbors seven year old twins over. Each had their own CAB and ran on separate loops. After about 10 minutes, the dash 9 suddenly would only run very slowly. I traded CAB's without any change. I then did a reprogramming to restore features. But the dash 9 continued to crawl along. The GE hybrid that the other twin was running ran normally. 

I had 3 suggestions which I followed up on but none worked:

 reprogramming to restore features

I oiled and greased the wheels

both motor/trucks assemblies are running

shut off the speed limit control

with the engine upside down in a cradle both trucks run when power is applied, but very slowly

in fact I can slow the wheels down by just applying a small amount of pressure with my clip.

The break slider is off on both CAB 2s

throughout everything the GE hybrid is running perfectly with both CAB twos

 

Being 89 years old and my hands being somewhat shaky I  did not open the engine. However some younger members of the club will undertake this for me.

Aside from broken wires, any ideas about what might be wrong internally?

Hi, with the engine on the tracks did you try applying full brake? Did the engine stop when you did? 

If the engine stopped try releasing the brake fully and see what it does.  The engine will retain the last brake setting no matter where the slider is if moved when not addressing that engine. 

You could also try it in conventional and see what it does.

Why don't you send an email to Mike Reagan (mreagan@lionel.com) on Monday morning describing this problem and see if he can diagnose the cause? You'll need to be in contact with Lionel anyway to get an RA so there's no harm in asking.

My own experience with kids under the age about about 12 or 13 handling CAB 2 remotes is that they can't resist/avoid pressing some button or pulling the train brake slider instead of the whistle/bell control. In that context it is dead easy to alter an engine's momentum settings as the relevant buttons are more easily accessible than they are on a CAB 1.

Either that or the Odyssey switch on the engine (which someone has already suggested you try turning off) struck me as the likely cause of your problem but an alternative is a problem with the motor driver. If you have both motors running at slow speed I'd suspect a settings/software problem rather than anything mechanical although in my experience Legacy boards of the kind that I think are in your engine seldom fail - or not without an electrical short somewhere. 

Good luck and tell us the result please.

iT'S SOLVED

Turning odyssey off , it would not even crawl!!

I reprogrammed to restore features but this time I assigned a new engine #. It runs perfectly!!!!!!!!!

Thanks to all of you for your input. A lot of trial and error and a little serendipity saved the day!

So that means that the engine number in the base has some max speed, etc. programmed in? Seems so. Lionel needs to get in on this. But maybe deleting the engine and then reprogramming with the same number would work as well.

Interesting - and weird and good, as stated above - I have had, over the years, a couple of TMCC locos that went weird on me - a rare occurrence, for sure - and re-assigning the (same or different) number cleared it up -didn't even need to do the Restore Features procedure. I call it the "Hello!" procedure.
