Bombardier IORE

By Yi -
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), the overhead cantenary system provides 15 kV, 16.7 Hz AC electricity to its pantographs.  The IORE weighs 360 metric tonnes and its total rated tractive effort (refer to the bottom of this post to revise what tractive effort is if you wish) at the wheels is 1,200 kN (269,800 lbf).  The total rated power output of the IORE at the wheels is 10.8 MW (14,500 hp).



For next week, if there are no other suggestions, I can talk about the MotivePower (a Wabtec company) MP40PH-3C diesel electric passenger locomotive used by GO Transit (part of Metrolinx) of the Greater Toronto Area.  (12 Jan., the MP40PH-3C will have to wait for a couple of weeks now at least.  We have the SD90MAC and something from Japan lined up next.)

8,000 tons? That ain't heavy! UP and BN do 18,000 tons of coal regularly in the west.

Trains that are a lot heavier than 8,000 tonnes are not uncommon in North America, Australia, and China. The point here is though that each unit of the IORE is designed to handle 8,000 tonnes, although you may argue that a unit of IORE is really 2 units stuck together.

i just found this blog. thanks for taking the time to share in this passion of trains! i love hearing about rarities like the IORE or the sd90 in the next post.

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

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

SD70ACu

After the post on the shiny rebuilt GE road power, it's only fair to have a look into what Progress Rail has to offer on their side of the table. I'm using the company's recently-changed, formal name of course. For those who are not up-to-date on the current state of North American railroading affairs, Progress Rail is the company (owned by Caterpillar) that purchased EMD a few years ago. The SD90MAC was arguably the biggest gong show in EMD's recent memory. It happened at a time when they were comfortably resting on their laurels, unaware the fateful changes that were about to occur in the locomotive market in the not-so-distant future (they got beaten badly by GE). What was supposed to be one of the most remarkable locomotives whose presence is to grace the mainlines in modern history, turned out to be an utter disaster (I'll redirect further readings to Wikipedia). As a result, today, the number of SD90s still in operation on a Class 1 Railroad is, if not id
