I purchased EZ track (HO) and 3 terminal rerailers to power the track. I purchased 3 so that I would not have a drop on the current on my 5' by 9' layout. I tried running all 3 thru a terminal strip with a terminal strip jumper. One side for the positive and one for the ground. The positive and ground are separated. It appears that when all 3 are connected to the track, the train does not run. Disconnecting two allows the train to operate. I am new to this gauge having spent most of my hobby time with "O" gauge trains and would appreciate any help. Thank you.
