hello !
I’m just wondering why a used MTH doodlebug might be a slow runner. Is it power supply (new style ZW w/ three bricks), or just the model itself. What causes slow running?

Frank,
Does it have speed control? - maybe the Locosounds version? If so, the speed control circuitry on these engines holds back some of the voltage, making them run slower than one without this feature. You might need at least 15 - 16 volts to get decent speed out of it.

On another front, Frank.... I was recently considering buying one of these at a thrift shop. It was about 10 years old w/ Proto Sounds 1. I held off as I was concerned about the battery issue. Did you run into any need to install the battery replacement unit on yours?
I had the same concern with my PS-1 doodlebug. As I learned from people here on the forum, MTH produced PS-1 doodlebugs both with and without batteries. Mine never had provisions for a battery; it ran off track power, had a 3 position E unit, and a nasally-sounding horn and headlight. But it runs great.
I hope this helps a bit.
It’s a PS2 protosounds version with a new battery. Runs well, just slower that everything.
PS2 speed control can be toggled on/off. The default is ON.

You won't get full speed out of a PS2 or PS3 locomotive in conventional. The electronics always keep some power in reserve for the speed control.
So I turned the Speed Control off and she flies. Thanks for all the help guys and sorry to be the RTFM guy.
Happy New Year!
