My wife picked out a Bachmann Trolley "item no. 62945 Streamline Trolley (ptc)"
I have a terrible time trying to figure out what decoder to use to covert to DCC.
I have Digitrax DCC.
It has to handle lights and motor. So which one?
I should of been more clear. I would like to stay with Digitrax. Also I am in
the U.S. and I have not seen those here.
What I have found is a DZ125. I believe this would work, just not sure. It is
just motor and lights.

There's no reason to stay with Digitrax, unless you want transponding.
Anyway, check the current draw of your trolley against the continual
current draw of the decoder.
To do this, use a multimeter ($3 at Harbor Freight or many internet
sites) set to 10 Amps and a standard DC power supply. Connect the
multimeter in series with one wire (so current goes through the meter),
and hold your locomotive down so the wheels can't turn and turn the power
on to ~12V. The reading you get is the maximum amount of current the
motor can draw. Don't hold the locomotive down any longer than it takes
to take a reading.
N and Z decoders often cannot handle as much current as their HO
counterparts, so it's well worth checking current draw. (I really should
put an ammeter on my test track...)

At .40A, that's well within the range of most decoders. The DZ125 is rated
at 1.0A, about twice your measurement so it should be fine.
Right now, I've got all TCS decoders except one SoundBug-equiped
locomotive. One of the members here gave me a good deal on a bunch of
older TCS T1s. They've worked very nicely with Digitrax control.
