British Rail Class 92 / SNCF CC 92000

By Train of the Week - February 21, 2014 I feel like writing about a little 6-axle Anglo French electric locomotive this week. By little I really only mean in physical dimensions, however, this locomotive is more powerful than any diesel in service in North America right now. She is used in transporting goods (or in freight train service I should say) domestically in Great Britain and through the Channel Tunnel between Great Britain and Europe. This locomotive is classified as the Class 92 in Britain and CC 92000 in France by the SNCF.

The Class 92 is quite a modern looking locomotive

The locomotive is jointly developed by Swiss company ABB and Britain's own Brush Traction. Since the Class 92 predates the High Speed 1 and has been built between 1993 and 1996, they have to have both a pantograph and the ability to draw current from the third rail DC system in the South of England. Due to the difference in electrical supply system, the maximum power developed by this locomotive differ. On top of a third rail, the Class 92 develops a healthy 5 360 horsepower; and under the catenary, that number becomes more impressive 6 760 horsepower. Although small in stature, 70 ft. by 8 ft. 8 in. by 13 ft. in fact, the Class 92 is more powerful than our massive SD90MAC-H at the wheels. However, the extra horsepower is meant for speed. European freight locomotives tend to be light and fast with what we consider very low tractive effort. In the case of the Class 92, the locomotive weighs merely 139 tons (vs. 208 tons for the SD90), a top speed of 87 mph in service, and develops a maximum starting tractive effort of 90 000 lbs. (vs. 200 000 lbs. for the SD90). Like most modern AC electric locomotives, the Class 92 is equipped with regenerative braking (dynamic only on 3rd rail). Since the Class 92 is used in the Channel Tunnel, most electrical systems have redundancies built in to prevent locomotive failure while inside the tunnel.

Nice and fresh coating on this DB Schenker unit

After the opening of the High Speed 1, Class 92 locomotives have received signal system updates to TVM (Transmission Voie-Machine) to allow them to operate on the HS1. There are currently 4 operators of these locomotives, GB Railfreight, Europorte Tunnel, DB Schenker in Britain, and SNCF in France. electric freight locomotive other

Unknown said… GBRF just bought 16 Class 92's from Europorte (their parent company)http://www.gbrailfreight.com/news.php?&newsid=1128Also DB Schenker have sent some of their locos to Eastern Europe - one is in Romania and up to five are in Bulgaria now. Feb 21, 2014, 7:50:00 PM

BNSF HH20B

By Yi - February 05, 2010

The train of this week is a locomotive unveiled in 2009 by the BNSF Railway. Instead of using conventional diesel fuel, it is powered by hydrogen fuel cells (I have very limited knowledge in this area, so please feel free to comment on this post if you are interested in and familiar with the topic of hydrogen fuel cells). It is called the HH20B, a hydrogen-hybrid switcher locmotive based on the GG20B Green Goat diesel-hybrid switcher built by Railpower Technologies Corp. of Brossard, Quebec (acquired by R.J. Corman Railroad Group of Nicholasville, Kentucky in 2009). The GG20B is powered by a 300 hp 4-stroke Caterpillar diesel-engine and a battery pack with a combined tractive output of 2,000 hp. On the HH20B, diesel engine is replaced by hydrogen fuel cells. Hydrogen storage is in a set of tanks installed on top of the long hood of the locomotive in a heavily vented enclosure, above the batteries. The BNSF Railway displaying its low- and ul... Read more

Briefly on the AAR Coupler Part 2

By Train of the Week - January 31, 2014

Last week, we've identified the Janney coupler and briefly looked at its elegant design. This week, let's, again, very briefly, look at the different types of Janney coupler that are widely used today. I will only talk about the head of the coupler, and ignore anything that the general public may need to trespass onto railroad property and get in a unsafe situation in order to have a good look at. As far as coupler heads are concerned, there are 3 types in used today. Type E, F, and H. Types E and F are used on freight, and H used on passenger equipment. Since the withdrawal of passenger service in North America by private railroads, the Type H standard is no longer maintained by the Association of American Railroads, a trade group formed of major freight railroads, but is under the control of the APTA, the American Public Transportation Association. Now let me introduce another term, slack. Slack is an allowed gap between two coupled up couplers. In other words, when most ... Read more

Amtrak NPCU

By Train of the Week - December 17, 2010

The NPCU or Non-powered Control Units are control cars used by Amtrak that are modified from surplus EMD F40PH locomotives. A control car is a generic term for a non-powered railroad vehicle that can control operation of a train from the end opposite to the position of the locomotive. They can be used with diesel or electric motive power, allowing push-pull operation without the use of an additional locomotive. Control cars first appeared in the USA and France in 1960s. Trains operating with a locomotive at one end and a control car at the other do not require the locomotive to run around to the opposite end of the train when reversing direction. In the United States, most control cars are modified from retired locomotives by removing tractive equipment and adding side baggage doors and have been used on several passenger railroads. The control cars are connected through the consist of the train by standard AAR 27-wire multiple unit jumper cables. The NPCUs at Amtrak are a... Read more
