Seems like the open plan layout of the new Overground stock is ideal

waiting to happen. With a long wide standing room only 'corridor'
running from one end to the other imagine what kind of a pile up of
bodies there could be in a Moorgate type crash. Or what would happen
if one train rear-ended another as a commuter train did in washington
recently. It seems to me that in creating so much standing room - with
very little to hang on to - that even an aggressive application of the
brakes - perhaps to avoid an obstruction on the line - would result in
a pile of bodies at one end. CJB.

AFIK these trains will not run into a terminal tunnel. This was a
major factor in the Moorgate crash. One hopes that we will soon have
signaling systems capable of halting trains before they can collide.
I have never seen the inside of these trains. I cannot understand why
they are not fitted with straps and a hanging rail after the manner of
tube trains.

Then, to me, they appear very suitable for their purpose.

If they would fit the loading guage, these trains would seem ideal for
District and Circle Lines.

....and indeed, the same factory is in the process of building
something pretty similar for District and Circle lines.

nitpick

As I understand the term, a 378 does fit the loading gauge ... because
the term loading gauge refers to the train itself ... so a 378 always
fits itself )

The comment I think should be ... if 378s would fit the SSL structure
gauge with sufficient clearance.

However, it is a Friday and I have a reputation of pedant to
maintain ... and I knew exactly what you meant )

Isn't it the case that the loading gauge is the maximum size of train
allowed to fit with the structure gauge. A train has to fit the
defined loading gauge for the route and this means it will
automatically within the structure gauge (plus clearance). So in the
UK we have routes being modifed to a W9 or W10 loading gauge for the
passage of the larger (9'6") shipping containers. In some places this
modification can be as simple as introducing a speed restriction
through a tight spot.

No.

There is a gap between the the loading gauge and the structure gauge -
the ''clearance'' I think the correct term is.

Nick, do you ever read all of a post before commenting?

"A train has to fit the defined loading gauge for the route and this

The loading gauge for a route is the minium space available once the
structure gauge and the clearance have been taken into account. In
most locations, the structure gauge will be actually be greater than
the loading gauge, but when looking at the route as the whole, the
loading gauge is the important describer as it takes into account
tight spots and relevant speed restrictions.

The amount of bars and straps doesn't seem all that high though; maybe
they don't expect so much overcrowding.

[trains around here are like a jungle-gym inside...]

It looks to me as if the straps were a last-minute addition, perhaps for
the benefit of shorter passengers. They didn't feature in earlier
photos, e.g.
