The DLR to Stratford runs
along the same GEML track after leaving the old goods chord from
Poplar.

The DLR line, from All Saints up past Devons Road to Bow Church uses the
former NLL Poplar line, which lost its passenger service during WW2, though
retained freight trains to the Docks until at least the 1970s. There was no
connection with the GEML - the NLL went under the GEML at Bow Junction. Now
the DLR swings parallel with the GEML, while the National Rail line from Gas
Factory Junction joins the GEML - this latter gets occasional diversions,
though has no booked passenger trains (and I'm not sure that there are any
regular ecs workings)[1].

The NLL Poplar line from there to Victoria Park has been abandoned, but at
Victoria Park (near Hackney Wick station) the line from Stratford joins.

It was electrified as part of the Shenfield electrification. The idea was to
run shuttles from bay platforms at Stratford to Fenchurch Street, but this
never happened. One of the bays has never been used; another was used for
the DLR until the DLR's own 2 platform terminus was built at Stratford.

Apart from the interest in the Olympic construction, this area is full of
railway history.
