Welcome to the Northern Line. Trains terminate at Euston quite
frequently when there are problems. I believe the Euston Loop comes into
play but someone will be along shortly to give the full details.

Euston is also a good place to hold the train to regulate the service,
i.e. hold as many pasengers up as possible as euston is where the sb
trains are the most full.

It's all about lights on screens not getting the most people there the
quickest.
