So this week we'll go across the Pacific instead and have a look at a passenger locomotive developed by the Chinese that's based on a popular Germany family of locomotives. China has apparently bought the technology to Siemens EuroSprinter and Bombardier TRAXX along with thousands of heavy-haul freight locomotives from Germany and they have been busy developing with the technology ever since.
Is it just me or does it look German?
So this locomotive, the HXD1D is a 6-axle locomotive designed to haul long distance passenger trains on China's existing railroad network (I'm guessing since Chinese passenger trains are long, around 20 cars, they need a bit of tractive effort with all the available horsepower and hence 6 axles). The latest government directive apparently dropped the maximum operating speed on existing railroads from 124 mph (or 200 km/h) down to 99 mph (160 km/h) and that's how fast this locomotive is supposed to go.
Interestingly the locomotive was fitted with a Type E coupler, this wouldn't entirely legal for passenger service in North America
Power output is slightly below the European locomotives on a per-axle basis (1200 instead of 1600 kW, or 1630 hp instead of 2175 hp, yeah, that's like a GP38-2 per axle or something). I'm not too sure of anything in much technical detail, the things I know are on the Wikipedia page linked here. Since this is an European electric, the only thing that's usual for those of us outside of the Northeast Corridor on this locomotive is probably the Knorr (New York Air Brake's Germany based parent company) CCB-II electronic brake valve.

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 Since the withdrawal of passenger service in North America by private railroads, the Type H standard is no longer maintained by the Association of American Railroads, a trade group formed of major freight railroads, but is under the control of the APTA, the American Public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