A Selection Of Train Noses

I have put together a selection of pictures of train noses.

They are in order of introduction into service.

Class 43 Locomotive

The nose of a Class 43 locomotive was designed by Sir Kenneth Grange.

Various articles on the Internet, say that he thought British Rail’s original design was ugly and that he used the wind tunnel at Imperial College to produce one of the world’s most recognised train noses.

  • He tipped the lab technician a fiver for help in using the tunnel
  • Pilkington came had developed large armoured glass windows, which allowed the locomotives window for two crew.
  • He suggested that British Rail removed the buffers. Did that improve the aerodynamics, with the chisel nose shown in the pictures?

The fiver must be one of the best spent, in the history of train design.

In How Much Power Is Needed To Run A Train At 125 mph?, I did a simple calculation using these assumptions.

  • To cruise at 125 mph needs both engines running flat out producing 3,400 kW.
  • Two locomotives and eight Mark 3 carriages are a ten-car InterCity 125 train.

This means that the train needs 2.83 kWh per vehicle mile.

Class 91 Locomotive

These pictures show the nose of a Class 91 locomotive.

Note, the Class 43 locomotive for comparison and that the Driving Van Trailers have an identical body shell.

It does seem to me, that looking closely at both locomotives and the driving van trailers, that the Class 43s  look to have a smoother and more aerodynamic shape.

Class 800/801/802 Train

These pictures show the nose of a Class 800 train.

In How Much Power Is Needed To Run A Train At 125 mph?, I did a simple calculation to find out the energy consumption of a Class 801 train.

I have found this on this page on the RailUKForums web site.

A 130m Electric IEP Unit on a journey from Kings Cross to Newcastle under the conditions defined in Annex B shall consume no more than 4600kWh.

This is a Class 801 train.

  • It has five cars.
  • Kings Cross to Newcastle is 268.6 miles.
  • Most of this journey will be at 125 mph.
  • The trains have regenerative braking.
  • I don’t know how many stops are included

This gives a usage figure of 3.42 kWh per vehicle mile.

It is a surprising answer, as it could be a higher energy consumption, than that of the InterCity 125.

I should say that I don’t fully trust my calculations, but I’m fairly sure that the energy use of both an Intercity 125 and a Class 801 train are in the region of 3 kWh per vehicle mile.

Class 717 Train

Aerodynamically, the Class 700, 707 and 717 trains have the same front.

But they do seem to be rather upright!

Class 710 Train

This group of pictures show a Class 710 train.

Could these Aventra trains have been designed around improved aerodynamics?

  • They certainly have a more-raked windscreen than the Class 717 train.
  • The cab may be narrower than the major part of the train.
  • The headlights and windscreen seem to be fared into the cab, just as Colin Chapman and other car designers would have done.
  • There seems to be sculpting of the side of the nose, to promote better laminar flow around the cab. Does this cut turbulence and the energy needed to power the train?
  • Bombardier make aircraft and must have some good aerodynamicists and access to wind tunnels big enough for a large scale model of an Aventra cab.

If you get up close to the cab, as I did at Gospel Oak station, it seems to me that Bombardier have taken great care to create a cab, that is a compromise between efficient aerodynamics and good visibility for the driver.

Class 345 Train

These pictures shows the cab of a Class 345 train.

The two Aventras seem to be very similar.

Class 195 And Class 331 Trains

CAF’s Class 195 and Class 331 trains appear to have identical noses.

They seem to be more upright than the Aventras.

Class 755 Train

Class 755 trains are Stadler’s 100 mph bi-mode trains.

It is surprising how they seem to follow similar designs to Bombardier’s Aventras.

  • The recessed windscreen.
  • The large air intake at the front.

I can’t wait to get a picture of a Class 755 train alongside one of Greater Anglia’s new Class 720 trains, which are Aventras.

Tortillas From Kings Cross Square

If you are arriving at Kings Cross station and feel a little peckish, it is often worthwhile to check out the offerings in Kings Cross Square in front of the station.

I found these delicious gluten-free tortillas last week.

A Quick Pasta Supper For One

A few months ago Marks & Spencer started selling an Italian made gluten-free passta, that is named prosciutto & ricotta cappelletti.

Marks recommend serving it with your favourite sauce or melted butter.

So I used one of my favourite sauces adapted from Serial Cooking – Quick Pasta For One. The idea came from a recipe from Lyndsey Bareham in The Times.

These pictures show the stages.

Note.

  1. I split frozen peas down into small one-portion pots.
  2. The yogurt is a small pot of Honey & Ginger West Country Luxury Yoghurt from Marks & Spencer.
  3. I generally drink Adnams beer!

I shall cook the second half of the pasta in a few days, which will be the fifth time, I’ve had the meal in three weeks.

Does This Bank Launder Money?

I always associate Tide with a brand of washing powder.

So does the bank of the same name launder money?

Travel Industry Confirms Rail ‘Renaissance’ In Europe

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

This is the introductory paragraph.

Assertions that long-distance rail services in Europe are rapidly becoming more popular as passengers eschew flying for environmental reasons were amply confirmed at the Rail Innovation Forum organised by Amadeus at its head office near Nice on October 9-10.

The article also gives these points.

  • Swiss Federal Railways are reporting a 26 % year-on-year increase in passengers for the first quarter of 2019 for night trains.
  • Sweden is reporting a 12 % increase in rail traffic and a 4 % drop in air traffic.
  • Flight bookings across Scandinavia are down by 10 %.
  • German long-distance rail travel is rising.

This all seems good news for carbon emissions.

Renewable Energy Outperforms Fossil Fuels For A Whole Quarter

The title of this post is the same as that of an article in today’s copy of The Times.

This is the introductory paragraph.

Wind and solar farms and other sources of renewable power have produced more electricity than fossil fuels for the first time in a three-month period.

This is a good figure, but how do we compare with the rest of the world.

This Wikipedia entry  is entitled List Of Countries By Electricity Production Prom Renewable Sources.

These are some example percentages of renewable energy production.

  • Albania – 100 %
  • Australia – 14.5 %
  • Belgium – 16.6 %
  • Brazil – 80.4 %
  • Canada 65.0 %
  • China – 24.5 %
  • Denmark – 60.5 %
