I also see that on the weekend of 12-13 May and 9-10 June that "Hatton
Cross - Heathrow Terminals 123" will be closed - I guess this is
connected to work on a junction for the branch to the new Terminal 5
station. Does this mean that trains will run:
Hatton Cross - T4 - T123 - reverse T4 - Hatton Cross ?

I very much doubt it, I suspect the whole loop will be closed. HX - T4 -
T123 is only single track so you could only run a train every 20 minutes at
best plus the signalling isn't set up for this.
