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

This is a movable switch diamond. It's more common than you would imagine. Although the switches mean more maintenance but these work quite well as there is no gap at the crossing, over which the wheel moves. A similar arrangement is the swing nose...

I have seen switch on a diamond crossing many times. Just before HWH station there are quite a few of them. The speed restriction on the diamonds before HWH is 5 kmph due to danger of derailment.
