The bulb curve is one of the safest and time-tested methods of turning a train at a terminus station. It is named so, because it is laid out in the shape of a bulb and helps a train move slowly and turn in the opposite direction. On December 31, 2018, as the empty six-car toy train on the UNESCO-recognised Matheran Hill Railway (tentative list) was negotiating one such curve at Matheran station — readying itself for a return trip to Neral, around 3.15 pm — a freak accident alarmed locals. The Matheran train had derailed again, and this time, during the peak holiday season on New Year's Eve.
