@david: "Anyone know what the plans are for the District line platforms at
Whitechapel?
There are two island platforms, originally numbered (I presume) 1 to
4. Plat 1 is the eastbound. The track has been lifted at plats 2 and 3
and the trackbed has been fenced off at both ends of the station. Plat
4 has been renumbered plat 2. This platform has been widened outwards
so the track has been re-aligned.  The old wooden canopy has been
extended to the platform edge by a new modern canopy along its length,
looks very odd!
Just wondered what the space in the middle will be used for since the
platforms have been renumbered.
And what have they done to the front of the station. Didn't it have a
proper canopy covering the full width of the front? Now it has a
couple of small glass protrusions above the entrance, hardly giving
any protection from the elements.

The two current tracks are in their final positions,  it will be the maximum 
size island platform that the space between the outer brick walls of the 
cutting will allow.

I believe there are also plans to take out the bay platform at Mansion

Given that the rebuilding of Tower Hill all those years ago made it 
redundant, why now? As Boltar says, getting rid of useful flexibility 
facilities looks very short-sighted.

There are new reversing crossovers at the east and west ends of the 
platforms.  One has to do a 'main line shunt' now and as this causes 
delays to the following trains is only used in degraded conditions.

I also notice that they have converted the signals in that area from 
automatic to semi-automatic, or floodgate signals, as they are called on 
the Northern Line. Why is that?
The semi-automatics on the eastbound track start just around near the 
old St. Mary's Junction and end just east of Whitechapel, about where 
the begin on the westbound track. The westbound semi-automatics seem to 
end at the starter on the westbound track."

I saw markers on the eastbound track between Stepney Green and 
Whitechapel, actually. One marker had C/R written on it, while the other 
had D/R.
Is that why they installed semi-automatic signals in the area, then?"

Not floodgate kmorris@example.com.  Semi-automatic (controlled) signals which 
are to be treated as automatic in certain circumstances.  When the 
points are proved  secured, the signal cabin can be put into King (the 
King lever is thrown) and worked as through running.

Probably very few - the point is that it provides a bolt hole and
gives flexibility in the event of problems.
Not aware of any specific plans.  There will always be a need to turn
some trains here in order to provide some paths for H&C trains running
east of Aldgate East.

Just going on what they call them on the Northern Line, though yes, they 
are semi-automatic. The illuminated A under the signal itself indicates 
that they are in automatic mode."

Of all the previous times that I have been there, it was only recently 
that I saw the lights with the illuminated A, both on westbound and

The draw-up signal on the eastbound track is still working, I note."

I've seen the illuminated As at Waterloo northbound on the Northern and 
at Russell Square on westbound track.
If the signals were earlier semi-automatic at Whitechapel, then why did 
they just install illuminated As now?"

Oh yes, it's not at all uncommon as I already indicated above, just that 
they are not timetabled moves; they will be a late running service being 
put back on time.

The area has been totally re-signalled with the work to remove the 
centre tracks.  There are no longer any booked reversers at Whitechapel 
so there is no need to keep the signal cabin manned.  When it is 
switched out and the As are illuminated, trains can be authorised past 
failing signals by the rulebook under failure conditions without the 
need for someone to go on the track and secure the points and then be 
authorised by the signaller.  If the points are not secured the As won't 
illuminate.

Drivers are taught how to identify Semi-automatic signals (basically any 
stop signal which doesn't have an Axxx number) and apply the appropriate 
procedure at a failing signal.
The signals at WHC are still semis, but in certain circumstances can be 
treated as Automatic; hence the A.

Floodgate signals all have an F and an X in the number; e.g. FNX78 at 
Leicester Square northbound.
The X indicates that they have to be treated as controlled and can't be 
passed under the Rule. There are other X signals (e.g. CX81 at Leicester 
Square southbound) that are so-numbered for train management or 
signalling purposes even though they actually work automatically.
LU uses the term "semi-automatic" to mean what everyone else calls 
"controlled", because they return to red behind a train even if the 
controlling lever is reversed and because they'll clear again without 
the lever being re-stroked. The ones with an illuminatible A are 
"semi-automatic that can work automatically".
