I agree with Greg about the 20va which at full 23volts to the track will not even give you 1 amp!!!! And this assumes you have nothing on the a/c output which will reduce the DC power. I recently found a 2nd hand 5 amp LGB power supply and speed controller with all the cables for a little more than the money you spent.
Also note that the MRC 20va can run 2 small LGB single motor engines, but not the smoke and passenger car lights.

I may have found some used LGB power packs, which model number do you get and I assume it works to run two locos?

I have the 5 amp power and 5 amp controller I bought used for $100.00US. 50111 is the power supply and can run LGB dc controllers or any of the LGB DCC controllers. LGB DC controller is the 51079.

These are directional, make sure the part number faces down!!
