China Railways HXD1

By -
North America has always been at the forefront of diesel traction in railroad heavy haul freight service. Although not heaviest in tonnage and not fastest in speed, our freight railroad system is balanced with longevity, interchangeability, and most importantly, service affordability.

Today though, I will write about a locomotive in a state-owned and operated heavy haul system where technological prominence is placed at a higher priority. The HXD1 is the first of the massive numbers of European electric locomotives China Railways has ordered in the early 2000s. Her primary assignment is the 10,000 tonne high speed coal trains on the Daqin Railroad.

The looks of the HXD1 show traces of the EuroSprinter
The HXD1 is an 8-axle electric locomotive with 2 permanently coupled sections. The locomotive is based on the Siemens EuroSprinter, and is built by Chinese manufacture CSR Zhuzhou under license.

The HXD1 combines some of the best Europe and North America can offer. With a combination of German vehicle engineering, AAR knuckle couplers, Knorr CCB-II electronic brake valve, and locotrol, 4 of this powerful, 12 900 horsepower, locomotive command heavy coal trains in an 1-2-1 configuration at a top speed of 70 mph.

This video down here is quite nice, nice long railroad bridge, some fog (or maybe smog), and a long empty coal train. You probably want to skip the first minute of pretty much just still image though.

Briefly on the AAR Coupler Part 2

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 Since the withdrawal of passenger service in North America by private railroads, the Type H standard is no longer maintained by the Association of American Railroads, a trade group formed of major freight railroads, but is under the control of the APTA, the American Public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

Amtrak NPCU

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

Bombardier IORE

For the readers who missed the posts in the past two weeks, we talked about the 110 mph General Electric diesel-electric locomotive P42DC Genesis (link here ) and once the flagship transcontinental passenger train of the Canadian Pacific Railway The Canadian (link here ). Let's take a break from passenger equipments and look at a very powerful freight locomotive this week.  The Bombardier IORE is a 12-axle twin-section electric locomotive designed exclusively for LKAB (Luossavaara-Kiirunavaara Aktiebolag), a Swedish mining company, to haul heavy (8,000 metric tonnes) iron ore trains (hence the name IORE) at 60 km/h (37 mph) in extreme Nordic weather conditions of northern Sweden and Norway.  It was first commissioned in Year 2000.  The IORE, or TRAXX H80AC, is an AC-propulsion locomotive that belongs in the TRAXX family of Bombardier locomotives.  The top speed of the IORE is 80 km/h (50 mph). The IORE uses 12 electric motors to power its axles (i.e. one motor per axle), t
