 On March 24 2011, 920M overran the dead-end platform at Macleod, crashing into the fence at the end of the platform.Prior to the accident, the platform had recently been washed and the soapy water had ended up on the tracks causing a complete loss of friction.Additionally, it was found that the end-of-line baulks (two wooden sleepers placed across the rails in lieu of a buffer stop) were also defective; the train wheels simply pushed them along the rails.
