A colleague of mine lives near the Liverpool Street to Chingford branch,
and is under the impression that the service has recently increased from
2tph to 4tph. He comments that the trains were previously half empty and
are now three quarters empty.

IMX the Chingford branch has never loaded very well, off-peak, between
Liverpool Street and Walthamstow Central. Often it loads better
Walthamstow - Chingford because of the interchange with the Victoria line at
the former, which draws away traffic to and from the West End.
