GOC YDM4 6132 had the honour of hauling a train – Cholan Express - all the way to TBM. Just like the good old days when the TBM-MS line used to reverberate with roaring YDM4 beasts bringing in Pallavan and Vaigai at a blistering 100kph. This is probably the first time that a YDM4 has officially halted at TBM! A passenger sits peacefully on the platform oblivious to the significance of the beast behind her. July1, 2004.
