Greetings, I have the Trainmaster base and remote but haven't been able to find the power cord for it. I've tried a lot of other home units to see if they fit but nodda. Anyone have any recommendations for scooping one up that could work as an alternative?

Also, the computer connection cable. Has any one daisy chained connectors to convert to USB connection?

The brick puts out 12VAC at 100ma, and that's it's rating.  Open circuit, it puts out a little more than 13VAC.

You can round up an AC output brick in the 10-12 VAC range and add the earth ground connection externally, that's what the 3rd prong does on the brick.  You can't use the much more common DC bricks, either regulated or unregulated, the command base depends on the AC waveform and has a circuit to sample for zero crossing of the power.

Nice find Rob, that's one I didn't see in my search!

You want to be careful picking the barrel connector, the command base uses a 5.5/2.5mm connector, not the more common 5.5/2.1mm connector you'll find on most of those cable assemblies.

For the transformer Rob points out, you'll want to connect the outside of the barrel to one of the transformer leads and the center lead that is connected to the round ground pin.
