150 DMs is all but 20 of the entire stock as built. It seems the

Am I missing something here??

Sorry. Finger trouble. The original idea was 4 car units.

Perhaps they'd be underpowered? They need to make up for their lower top
speed compared to Pacers with a higher acceleration.

The initial reports of 4-car units were probably more speculation than
fact. After all, in LU service they run as pairs of three-car units, with
only one trailer per pair of power cars, and the plan seems to be for the
same in their new lives as DEMUs. To run as four-car units would probably
require the 4th car to be an UNDM.

The whole thing seems crazy to me. Why don't they just get some 170s or
something? Why re-engineer metro trains with a top speed of 40 mph that
have little in the way of crash protection?

Also I'm curious to know how they'll deal with the loading gauge issue.
LU surface stock is wider than mainline stock.

The top speed is 60mph. And they can't buy new 170s any more, as they're
not emissions compliant. In any case, the D-Trains will be far cheaper. The
D stock is already mainline certified, though it'll be getting extra
collision protection around the cabs (which also means they'll look
different).

Also I'm curious to know how they'll deal with the loading gauge issue.

The D stock was always mainline certified.

Another EU triumph.

In that case presumably so is the 9 foot 7 wide S stock which runs on the
same NR lines. Which makes me wonder why they don't build wider mainline stock
then instead of the pokey things they dish up these days where the seats are
never quite wide enough.

About half the cost in fact.

If you mean to avoid the destruction of the planet, then yes.

I suspect the S stock isn't passed for use outside the Chilterns route which
was originally Metropolitan, not BR predecessor, built.
