Today's post is again, inspired by a news article I read online. Apparently, National Express has just unveiled their Talent 2 trains that are set to enter regional services in Germany a year from now. I'm sure the original Talent isn't too strange to riders in Europe, although some may not know that is her name. In fact, a few of them can even be found in North America if you look carefully enough. The O Train for example, a short stubby commuter rail line in the Canadian capital of Ottawa, is a diesel version of the original Bombardier Talent.
Pretty nice looking little thing really
So the Talent 2 is an articulated regional EMU that comes in 2-6 car consists. The trucks on the ends are powered and every other one in between are powered for sets longer than 2 cars (so therefore, 2 and 3 car sets have 2 powered trucks, 4 and 5 car sets have 3, and 6 car sets have 4). Each truck has an power output of 1 010 kW or 1 354 Her Majesty's horsepower, you figure out how much power in total these different consists can pump out.
Interior of the DB Talent 2, pretty simple and clean
With a top speed of 100 mph, the Talent 2 is designed to operate regional services on the mainline. As usual, this Wikipedia page will tell you more, and way more about this little trainset, her operators, routes, etc., and a link from it will probably tell you what S-Bahn exact is (you might need Google Translate, the English page of Talent 2 doesn't really say much at all).

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...
The ES44AC (successor of the AC4400CW) is a member of the family of GE's latest and greatest diesel-electric freight locomotives, the Evolution Series . Other locomotives in the Evolution Series include ES40DC, ES44DC, ES44C4 for the domestic market and ES44ACi (Kazakhstan), ES59ACi (China), and ES44DCi (Australia) for export. The direct competitor of the ES44AC is the SD70ACe developed by Electro Motive Diesel (EMD). The name ES44AC can be simply decoded as E volution S eries 4 , 4 00 horsepower AC traction (this naming scheme does not apply to EMD products or the ES59ACi which actually outputs 6,250 horsepower). However, unlike electric locomotives, the rated power of diesel-electric locomotives are measured at the prime mover (i.e. the diesel engine), not at the traction motors. The Evolution Series were developed to meet the stricter EPA Tier 2 emission standards. These locomotives use the GEVO prime movers instead of the FDL prime movers used on th...
What makes most trains, trains, is the fact that locomotives and cars are interconnected by some mechanism (of course they no longer had to be since the introduction of the rail diesel car) that allow them to move along the railroad tracks simultaneously. Before I go further, I wish to introduce, very briefly, buff and draft forces. Two cars are in buff when they push against and are in draft when they pull against each other. A little bit on history: at the very beginning, this mechanism that connects cars together are made up of separate components that deal with buff and draft forces individually. The link and hook take care of draft forces, and buffers (they look like pancakes sticking out the ends of trains as seen in Thomas the Tank Engine) deal with buff forces. Although this system works well once the coupling is complete, which is why it is still in use in many parts of the world, there are many disadvantages to this primitive coupling system that make it unacceptable ...
