Stratford International

Could someone tell me where the line that comes off HS1 at Stratford and then goes over it goes.

 

It goes to the Eurostar depot at Temple Mills.

 

The Red Cross is where you are in the picture. And the highlighted blue line is where it goes- as WonterRail says, it goes to Temple Mills depot.

 

Ballast looks too pink, WTF DTG!!
