Had a view of the District Line track replacement works between Barking and
Upminster yeaterday, from a passing c2c service. I was wondering what short
of length they can do in a weekend, and if the renewed track is basically
done to the same standards as NR use, eg sleeper spacing, ballast depth etc.
I noticed the same orange tubing guarding cables in the four foot for
instance.

Not sure, but I noticed new track on the Met at Euston Square last
week, and was astonished to note that it was of the jointed, bullhead
variety.

When are LUL going to enter the 21st century and move to CWR like the
mainline did years ago?

Within the confines of tube and sub-surface tunnels one would think
jointed track easier to work with than CWR.

That IMU is the main reason for its continued use, IIRC there often
isn't sufficient clearance to allow use of the necessary equipment for
laying and fettling CWR and some of the curves would also invite
trouble. I've got an old programme for an open day at Neasden in
196mumble which features a CWR train so it isn't something LU have yet
to discover.
