Departing Stock

In article

Post by Recliner
Apparently this Frday (21st) will be the last for the D-stock in normal
service in London. I believe there will be a farewell tour on 7 May.

Indeed so. A working timetable diagram has been announced but not confirmed.
It starts at Upminster at 0624 with runs to Richmond and back arriving at
Upminster at 1623, departing 1635 to Ealing Broadway at 1812. I fear we
won't know if it's actually running then on Friday morning.

The May 7 tour tickets went on sale only this morning and are almost sold
out, despite costing £50, with space in only one car of six still available.

After that, of course, there may be opportnities to travel on them on new
routes, with an unfamiliar diesel rumble under the floor.

Maybe. With the current cost of new rolling stock, I wouldn't count on it. I
mean, if brand new SWT class 707s can be discarded...

Well, as no doubt many here know by now, it did run as train 4 as planned. I
joined it a bit after 12:23 at Aldgate East eastbound, as did 3 others (not
hard to spot people waiting on the platform :-)). I then rode it to
Upminster, back to Richmond, back to Upminster and from there to Ealing
Broadway. It got pretty crowded at the front at times! Before I joined it,
it had accumulated 20 minutes of delays and been turned short at Gunnersbury
on the westbound trip before the eastbound I joined.

We got a bonus rare track move when the final run was put through the West
Ham siding westbound to allow trains (3 in the end) to pass us to presumably
avoid it to get too crowded. That siding has a diagrammed H&C working but
only eastbound. So few will have used the westbound crossovers to access it.

All gone now.

I also got the chance to travel on the Circle on Saturday while it was
running as a real circle again this weekend.

Do you know how long it is taking to go around? Is there a four minute
wait at Edgware Road?

I don't know, I'm afraid. Mine didn't wait as long as 4 minutes I think but
the stop was slightly extended to allow a westbound Hammersmith & City train
to depart from platform 3 first. The centre platforms were reallocated for
the duration, with Wimbleware trains reversing in platform 2, the usual
Circle terminating platform while H&C trains were reversing from west to
eastbound in platform 3, usually the Wimbleware platform since the tea cup.
They didn't seem to have changed or annotated the platform signs though.

Westbound H&C train?
The "Weekend travel information" email said:
"Hammersmith & City line
Trains will not run between Edgware Road and Hammersmith. This is to
allow us to test new signalling and replace track at Latimer Road."

Adrian Shooter seems optimistic that more orders are in the pipeline. The
EMT trial would not, in any case, have led to a significant order, even
without the fire. In a way, the fire was a good thing, as it uncovered a
number of weaknesses that might not otherwise have come to light till much
later.

Vivarail also has a battery version entering test.

IMO the main weakness is using van engines at all. Safety issues aside long
term reliabilty is going to be a serious issue as these engines were never
designed to be worked at max power for hours on end then spend another few
hours idling almost 365 days a year. Their capacity is small meaning the
max power rpm will be much higher than normal railway diesels and hence
increased wear and tear. I'm sure the company would point to the ability
to swap out the engines but really, who is going to want to spend the time
and money replacing knackered engines every few years?

all the time these days?

Yes. Though I suppose one of the four power packs may need to be left
running at a terminus. And the D-train's duties certainly won't involve
running at "max power for hours on end".

Greater Anglia's battery-EMU project has disappeared without trace.

It was a trial that tested what it was supposed to. It found that the
technology works, but battery costs need to come down more to get a
reasonable range on the batteries. It's really no different to
electric road vehicles: if you want a decent range and performance,
they cost a lot (see Tesla vs Leaf).

Perhaps the battery D-train (or is that E-train?) will keep costs down
by having smaller battery packs, which may be adequate for its lower
speed and shorter range?

Yes, and they'd clearly not put enough effort into the task. Vivarail seem
to have tried to simply outsource the whole power pack to a local firm,
which obviously bodged it. The proven Ford engine may be up to the job, but
how it's mounted in the power pack (plumbing, wiring, fire-proofing, etc)
is at least as important.

Van man will only be thrashing it for an hour or 2 each day. The rest of the
time it'll be parked up outside the building site or wherever. It won't be
trying to accelerate and maintain the speed of 10 tons of carriage most of
the day then spend the rest of its time idling since apparently train drivers
don't know where the off switch is it would seem. This isn't a static generator
generating a constant 240V at a constant RPM, its got a duty cycle and it'll
be a hard one for a small road vehicle engine.

Train engines work hard to get the train up to crusing speed (60 mph for
these trains). That takes a few minutes. The rest of the time they're
producing very little power. The engines will cut out automatically when
power isn't needed, just as road vehicles do.

Train engines work hard to get the train up to crusing speed (60 mph for
these trains). That takes a few minutes. The rest of the time they're
producing very little power. The engines will cut out automatically when
power isn't needed, just as road vehicles do.

Road vehicles can get away with that because the transmission keeps the
engine spinning so no restart is needed - the ECU simply starts injecting
fuel again. That won't work with a generator engine.

Mostly the engines stop in road vehicles when the vehicle is
stationary, so the starter motor is needed. With the generator
modules, I wonder if they can use the generator as the starter motor?
If not, then they just have a conventional starter.

I don't think many vans have start/stop though I could be wrong.

More than likely.

It must be noted from the reports on the fire that there are
genuine issues with making the power packs compatible with a rail
traction environment. Fascinating.

Yes, and they'd clearly not put enough effort into the task. Vivarail seem
to have tried to simply outsource the whole power pack to a local firm,
which obviously bodged it. The proven Ford engine may be up to the job,
but how it's mounted in the power pack (plumbing, wiring, fire-proofing,
etc) is at least as important.

The other point being that systems regarded as adequate for the roads most
definitely aren't acceptable as safe for rail use. We put up with incredibly
low safety standards in road vehicles.
