You don’t have enough power.

Are you using DC or DCC ? How many locos do you want to run at one time ?

So are you actually running 20 locos at one time ?

What do you mean by a “transformer with the power unit removed” ? (A transformer is a power unit.)

I have no personal experience of it so maybe another respondent can put more meat on the bone so to speak.
