How can I get from Heathrow T5B to T5A?
I am taking a domestic flight departing from London Heathrow Terminal 5, probably T5A. A family member is taking an earlier international flight that same day, probably departing from satellite terminal T5B. If I accompany him to his gate, how can I make it back to T5A to catch my flight?
Update: Sorry, I didn't make the problem clear. There is an automated people mover connecting the main terminal to 5B, a kind of mini-train. However - my understanding is that outbound and inbound flow is segregated, as incoming passengers have not yet cleared UK immigration. From memory, when the train arrives at a satellite terminal, doors open on one side of the train to allow outbound passengers to proceed to departures. The doors then close, and members of staff ensure the train is empty. Doors then open on the other side to allow incoming, non-immigration cleared passengers to enter the train. If I were to attempt to enter the train from the departures side, I am expecting to be made to leave again by staff. Do I remember wrongly, or is there a way around this problem?

A couple of years ago, I was in a similar predicament: I had a long time to wait before my departure from T5A, so decided to explore T5B out of curiosity, and only realized that the trains are one-way after getting there.
I asked a member of staff for help, and she helpfully informed me that there are pedestrian tunnels running alongside the train tunnels. She told me to go back down to the station and find a security guard who would direct me to the pedestrian route. In the event I didn't find any security guards, but the door to the pedestrian tunnel was easy to find and not locked. The tunnel itself was impressively large (I think it's sized to be suitable for emergency evacuation). I didn't see anyone else there but I didn't get the impression that I was trespassing on forbidden territory: it seemed to be designed for public access, even if the possibility isn't publicly advertised.

Answer 2
Just speak to a member of staff at the terminal and they can direct you to the correct place to board the return train - this happens all the time with accompanies passengers and also people who have gotten off at the wrong stop, don't for a moment think you have an unusual situation :)
