Resting after conducting a number of emergency stops, the first 5000 AC propulsion is at Bryn Marw on track one. The 5000s were deliberately designed to be look-alikes to the 3200s.
The first round of tests today were evidently service braking from full speed. The Bombardier 5000s are shown accelerating next to Granville in this tele shot from Thorndale.
During the braking tests, the 5000s try to catch a neighboring Red line train.
In order to insure the new 5000s don't break down going through the complex Howard Street interlockings, the test cars are hauled by four "horses" made from an eight car drag from Howard Yard. The other four cars make up the buffer train that will follow. The two sets of cars are parked at the ends of track one leaving about 3 miles in between for testing. This photo shows the horses hauling 5012/5011.
