Over the weekend, crews preformed trouble shooting on car. Baltimore Transit PCC #7407 was not building air properly. We started doing some tests. The needle will stop at approximately 65PSI, the compressor will run as intended, it will keep going after the needle stops. Then shut off, Acting like it was building to 90PSI. We did a test trip to see how the brakes felt (thinking the PSI gauge was the issue). We also found a leak for the air drain, while searching for it i noticed another drain on the second tank, which I opened and it ran water out of it for approximately 45 seconds to a minute.
