Photo of the Day: Harmonic Testing

On Sunday morning Transdev/Kiwirail conducted a large scale test of our electric trains. I understand the trains had been creating harmonics through the lines. This wasn’t affecting trains but was creating impacts outside the network – although I’m not sure of the full extent of the issue. The test saw seven 6-car EMUs running between Papakura and Britomart via the Eastern Line which I believe is the most electric trains that have run on the network at any one time so far. When two EMUs are joined together they have the capacity to comfortably carry 750 people although during an event or during a busy peak I suspect that number could be closer to 1,000.
