Hauling With Hydrogen: DHL Adding Fuel-Cell Vans To Its Delivery Fleet

The title of this article is the same as that of this article on Forbes.

This is the first paragraph.

Hydrogen is the most abundant element in the universe, but vehicles powered by the clean fuel are somewhat scarce. In the latest sign that that’s changing, DHL is adding hydrogen fuel-cell vans to its fleet to cut carbon emissions with faster refueling time and longer-range than battery-electric vehicles offer.

The whole article is well worth a read.

Conclusion

This initiative by DHL, like the development of hydrogen-powered double-decker buses for London and Liverpool, is another well-thought out project to move the world towards a zero-carbon and low pollution future.

All three projects are multi-vehicle projects, where fuelling can be done on a centralised basis.

Looking at the large cities of the UK, there must be several large fleets, that could be converted to hydrogen.

  • City buses
  • Royal Mail and other parcel and mail delivery vehicles
  • Taxis
  • Refuse trucks

I can see a range of solutions for providing zero-carbon and low-pollution transport, which vary dependent on the application and fleet size.

Specialised bicycle systems – Locally, I’ve seen bread deliveries, a nappy service and a plumber. There was also an item on the BBC about a hospital using a bicycle for local deliveries of samples, drugs and blood.

One-vehicle electric vehicle systems – Many small busineses, trademen and house-owners have a vehicle that they keep off the road in their premises or garage. A pathway needs to be developed, so that they can exchange their current vehicle for a battery-electric one, which also plays its part in storing surplus electricity. The technology is there, but it needs to be packaged, so people can afford to take that route.

Multi-vehicle electric vehicle systems – This is obvious for companies with lots of delivery vans, but this could be extended to blocks of flats and office developments, where all parking spaces have charging points and service charges could be set to encourage electric car use.

Multi-vehicle hydrogen systems – I’That’s where this article started and I think, this could expand, as the technology of both the vehicles and the hydrogen fuelling improve.

,There could be lots of niches, which a tailored-solution could solve.

The Cement Truck Example

I would love to know how many miles the average cement truck does in a day. But obviously the companies know and calculations would show the size of hydrogen tank needed for a couple of days work in a city like Leeds.

  • Range with a full load wouldn’t be more than perhaps fifteen miles.
  • The return trip would be empty and needs less power.
  • The depot would have a hydrogen fuelling system, Fuelling a hydrogen truck should be no more difficult than fuelling a diesel one.
  • Whilst in the depot, if power is needed to turn the drum and mix the cement, this could be provided by a direct electrical connection.
  • The truck could leave the depot with a full battery.
  • Hydrogen trucks might be used for local deliveries with perhaps diesel hybrid trucks for longer deliveries

I suspect that looking at the system as a whole entity could produce a very good system.

If say it cut carbon emissions and pollution by upwards of fifty percent, would it give the company a marketing advantage.

Perhaps, each building should be taxed for the amount of carbon dioxide and pollution its construction created?

Vivarail Units Take Over Marston Vale Services

The title of this post is the same asw this article on Railway Gazette.

The article contains an informative video of Adrian Shorter talking about the Class 230 train.

Much of the article and the video is information that has already been well reported.

Adrian Shooter does mention that the diesel-electric-battery versions of the Class 230 train for Transport for Wales will incorporate geo-fencing.

This would mean that in sensitive areas, the diesel engines would be cut out and only  battery power would be used.

The process would be controlled automatically using the train’s position from GPS.

This technique has been used on hybrid buses to lower emissions and noise levels in sensitive areas.

InterCity Quality For Rural Routes

The title of this post is a quote from the Managing Director of Greater Anglia; Jamie Burles about the Class 755 trains in this article on Rail Magazine.

This is the complete paragraph.

Burles said of the Class 755s: “These will be the most reliable regional train in the UK by a country mile – they had better be. They will be InterCity quality for rural routes, and will exceed expectations.”

Initially, the Class 755 trains will be deployed between Norwich and Great Yarmouth stations.

  • It is 18.4 miles long
  • There are four intermediate stations.
  • Trains currently take thirty-three minutes.

It is certainly not your traditional InterCity route and it only runs at a maximum frequency of two trains per hour (tph).

Consider.

  • Norwich is a City of over 140,000.
  • Great Yarmouth is a town of 40,000.
  • There are lots of business and leisure reasons to travel between the two.
  • The A47 road between the two is totally inadequate.

Greater Anglia are purchasing a fleet of 38 trains with a total of 138 carriages to replace 27 trains with a total of 58 carriages.

  • This is a forty percent increase in the number of trains.
  • This is nearly two and a half times as many carriages.
  • The average number of carriages per train is raised from 2.1 to 3.6.

That is a massive increase in train capacity.

I don’t believe that Greater Anglia will park these trains in a siding, but use them to increase frequencies.

  • Will the 100 mph operating speed of the trains allow a round trip between Norwich and Great Yarmouth to be done in after an hour?
  • Will the frequency be increased to up to four tph?

If this can be arranged then Greater Anglia could need as few as four trains to run a Turn-Up-and-Go service between Norwich and Great Yarmouth.

How many passengers would that attract to the route?

Comparing Three-Car Class 755 And Class 170 Trains.

Some three-car Class 170 trains were bought some years ago, to run services between London and Great Yarmouth.

In recent years, they have become the mainstay of Greater Anglia’s regional routes.

  • Ipswich and Cambridge
  • Ipswich and Peterborough
  • Norwich and Cambridge

All three routes are currently run at a frequency of one tph.

These trains have the following specification.

  • 100 mph operation
  • Two-class layout.
  • Between 100 and 200 seats.

They have proven to be a  capable train for the routes and appear to have been driving increasing traffic levels.

It should also be noted that other operators use these trains on routes including.

  • Birmingham and Stansted Airport
  • Cleethorpes and Manchester Airport
  • Cardiff and Nottingham

I think it is true to say that Class 170 trains are 100 mph trains for running on InterCity routes that can’t justify a full-size train like a bi-mode Class 802 train.

Some operators will also be running five-car Class 802 trains on routes that have been run in the past or still are run by Class 170 trains.

The Class 755 trains are 100 mph trains, which Greater Anglia are using in two sizes.

  • Class 755/3 train – three cars with 167 seats
  • Class 755/4 train – four cars with 229 seats

The longer trains will probably be used on Greater Anglia’s longer regional routes.

  • Ipswich and Cambridge
  • Colchester and Peterborough
  • Norwich and Stansted Airport via Cambridge
  • Liverpool Street ans Lowestoft via Ipswich

Note that the last three routes are electrified for nearly have the route.

Except for the Ipswich and Cambridge route, these routes are longer than those run in the past and these routes will probably need four-car trains with InterCity interiors and service.

The Liverpool Street and Lowestoft service of the 1960s and 1970s had a buffet car and passengers on this route will at least expect a trolley service of drinks and snacks.

I very much feel that the Class 755 trains will in a worse case be better than the Class 170 trains, that have run InterCity services in the past.

Will Class 755/3 And Class 755/4 Trains Have The Same Interiors?

Greater Anglia haven’t said definitely that the interiors in the two classes of train will be the same, but I think it will be likely, with respect to the ease of building and maintaining the trains.

This video shows the train being tested at Diss.

Unfortunately, it doesn’t show the interior.

So I’ll have to wait until the end of June to have a look at a real train.

It should also be noted that Class 755 trains can be lengthened by adding extra trailer cars.

So it would be unlikely that the interiors in the driver and trailer cars were different, as this would mean that shuffling of cars could create a train with a mixed interior.

Conclusion

Consider.

  • Some of the Class 755/4 trains will be running InterCity services.
  • Both Class 755 variants are capable of 100 mph running.
  • Ease of building and maintenance probably requires identical interiors.

It would appear that all services where Class 755 trains are used, will get the same InterCity passenger experience.

Although some services could be slower than InterCity services, due to track limitations.

Will Abellio use a similar philosophy, with the new fleet for East Midlands Railway?

Hither Green Station To Go Step-Free

This document on the Government web site is entitled Access for All: 73 Stations Set To Benefit From Additional Funding.

Hither Green station is on the list.

These pictures show the station and the current bridges,

Like Petts Wood station, which I wrote about in Petts Wood Station To Go Step-Free, Hither Green station is a rather unlovely assemblage.

  • It has all the qualities of the worst corrugated iron buildings.
  • There are five flights of steep stairs.
  • There are two separate bridges.
  • Entry to and exit from the station are from a subway, that links to Platforms 4 and 5.
  • To access Platforms 1,2, 3 and 6, a bridge must be used.
  • I suspect that some interchanges may need crossing both bridges.

This Google Map shows the station.

Note the three pairs of tracks, with six platforms and two bridges.

In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.

So could a factory-built bridge like this be installed be installed at Hither Green station?

This bridge has the great advantage, that it can be installed without closing the existing bridge.

This Google Map shows the South Eastern section of the station.

Could two bridges linked ny an aerial walkway across the woods be added beyond the covered parts of the station?

Some interchanges would be a walk of perhaps a hundred metres, but they would be fully step-free.

The rest of this terrible station would be left untouched and could be gradually improved in the future.

Silicon Roundabout Goes Two-Way

Old Street Roundabout, commonly known as Silicon Roundabout has now gone two-way!

But as these pictures, which were taken around nine in the morning, show, it is a traffic nightmare.

It’s not good for pedestrians either and I now use the trains from Angel or Essex Road to go safely underneath at busy times.

Surely the big problem, is what do you call Silicon Roundabout?

Will 5G Be Another Way To Rip Off The Poor?

My late wife was a barrister, who specialised in family matters, like divorce, custody of children, adoption and money.

She had this career for about thirty years before she died in 2007.

As the years progressed, she’d talk about the latest expensive must-haves of her clients.

  • First it was video recorders and then it was mobile phones.
  • Various game consoles arrived! Whatever they are? I’ve never played a computer game in my life!
  • Then came Sky Television and large screen televisions.
  • Every child had to have the latest phone.

And now we have 5G, which promises to be the next unaffordable addiction, to go along with alcohol, drugs, pay-day loans, junk food, on-lne subscriptions and gambling!

It will drive the poor and low-paid even further into poverty.

On the train recently, I was talking to a guy with nine children.

As he was going to Court to get custody of one of the nine, and from other things he had said, I felt that the nine weren’t of the same mother.

He was living on benefits and caring for one disabled child.

How will he be able to afford nine 5G phones?

It’ll all end in tears!
