Why cannot more mainline trains be a little longer (by a carriage or two)
and overhang platforms at the back?

It happens on various rural routes and seems to present no problem.

The Elfin Safety people won't allow it. And surprisingly a lot of modern
trains simply aren't equipped with sufficiently sophisticated selective
door opening.


As I've mentioned before, TOCs such as SWT use SDO by whole unit, sometimes
only releasing the doors in 4 coaches of 12; or using single door only in
444s at 4 platform stations such as Beaulieu Rd, or Shawford.

Happens routinely on the mainline platforms at Clapham Junction too, so the
rural bit isn't a requirement either.

Thes trains do not have 'grandfather rights' - so the H&S issues presumably
can be overcome if required - you can nearly always find an example of
something happening on the railway that they say 'isn't possible' somewhere
else...

The Whistling Fellsman tour - 13 Mk2's (plus a generator coach) - set
down at Denton last night with no problems.

But then there were plenty of stewards to make sure passengers were
moved forward to the first 3 coaches in order to alight safely.

Do those trains have a corridor connection between each set of 4
carriages?

One of the major design flaws in the networkers on the Cambridge line is
that they don't.

The 5-car train I mentioned earlier was made of three units (2+2+1) and
not only was there a corridor all the way through, the connecting doors
were open so you could see all the way through the train!

Yes - and so do Southern, (on their EMUs) which also have the benefit of SDO
by carriage number, rather than whole unit.
