Testing the track and making adjustments. It seems that flaws in the track work are more evident with a train on it. The benchwork design makes adjustments quite easy. Here is a cut of 16 autoracks on the left most loop. The locos are on the track that has soldered leads. The tail of the train is on track that is powered only by the track connectors. The motive power is a BLI AC6000 BNSF and an Atlas GP35 SP, both MUd together. The train is on a 1% grade going uphill.
