Switch in Diamond? - A Unique setup found only at Thane Station outer of Central Railway Mumbai section, not found anywhere on IR - 2 switches inside the diamond crossing layout. They have never ever been used till today. Even if its used, only EMUs will be able to cross and not more than at 4kmph, else, it will defintely derail as the angle will be too sharp. The switches change only when a semifast train changes over to slow corridor. - by Vijay.A
