AFAIK, the Widened Lines to Moorgate were unelectrified until the time
of the BedPan electrification, whereupon OHLE was put up. They've
never had 3rd or 4th rail (unlike the adjacent LU tracks).

AIUI the eastbound Widened Line was electrified (4th rail system) between
1926 and 1935, when Met trains terminating at Moorgate used the Widened
Lines from a crossover at Kings Cross to the terminal platforms at Moorgate.
In the reverse direction the Circle line track was used. This reduced
conflicts at Moorgate. This arrangement was abolished in 1935 when the Kings
Cross (Circle Line) was relocated from its original position adjacent to the
current Thameslink station to its current position.

It puzzles me that LU insists on running Met Line trains thru to
Aldgate. The Junction there must be an operating challenge. Meanwhile
there is ample unused capacity at Moorgate. Surely the walk saved to
City employment centers cannot be so much shorter from Aldgate?
