No, the solution is, as Tony P has suggested earlier, is to lay in a loop and shift the platform back to the straight section. I
have checked this using Google Maps and it is just possible to get in a 25m radius loop IIRC (it may have been an 18m radius -
forget now). 25m or 18m are easy to use for modern trams.

This loop just clears all the buildings on site, though IIRC it would help if it were to cut into the rail reserve - there should be
no problem doing this for a few yards.
