Do the DCC equipped EMD FT A-Unit and B-Units work together to provide better pulling power? The A and B are both sold separately and both are powered but I cant find any info on them working in tandem. I'm assuming that they do.
They should be able to, have them on the same channel on your DCC channel and give it a try. They're basically the same build, except the shell.
Sir-
You must be sure to program the B-unit such that forward and reverse match the setting or the A-unit. The two locos will work against one another if this is not done. You might also have to speed match the locos but I would guess that this is only a minor issue, if it's an issue at all, since they are the same under the hood.

out of the box most new locomotives have the dcc address 03. thus your ft a & b should work together. if the b unit runs the opposite way from the a unit, turn it around. and when you reset the address of the a unit, set the b unit to the same address as well. and keep in mind that unlike later versions of f units like the f7 and f9, many fts were semi-permanently coupled in a-b pairs, and many ran their entire lives coupled to each other.

I have the FT A & B, together they will be pull 25, 50' free rolling cars up my 3% incline without a problem, part of my incline has a 22" curve at the start.
They do have the pulling power, now that they are broken in I may add a few more cars to see where they max out.
Just make both units the same address number, put them on the track & power them up to see which end of the "B" unit goes in the same direction as the "A" unit.
Hope this helps with the pulling power part of your question.

I have several AB sets and two ABBA sets. These locomotives seem to work well together. Unless a decoder goes bad.
