Hi I think it the KYN end side of TNA. If yes, then it is in use. I think it is connection of FAst Dn line to Slow Dn line.

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 crossing used in high speed turnouts these days.

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.

Thanx Samit for all the efforts that you have taken. Really came to know a lot about different station names around Howrah.

Very informative. Cleared by long-standing doubts about some of the lines in and around HWH.

Excellent work, Samit. Very Useful for quick reference.

Rajeev Sir, can you kindly explain this to us on the forum?

The MG line between BRY and Izzatnagar (MGline) is a double line too with proper MACL in place all the way uptill Malani

Other local trivia: Izzatnagar is actually named after one Charles Izat who was the GM of one of the older companies, while the extra Z got added later. Izzatnagar station may well be the smallest station to have a divisional HQ.
