Indian Railways WDM-2

By -
Back in the days before General Electric got big into building locomotives, there was this famous company called American Locomotive Company, or Alco. Similar to today's major builders, their locomotive also sold across the globe. Right, my title gave it away. This post is about an Indian locomotive designed and first by Alco in 1962. Starting in 1964, India produced this locomotive domestically at the Indian Railways' very own Diesel Locomotive Works.

Started life as the DL560C, 40 units of this Alco and 40 EMD SD24 were produced in America and shipped to India for trials. Compared to the SD24, the DL560C was deemed more reliable and rugged. With the added benefit of a technology transfer agreement from Alco for domestic production and simple maintenance, India went big on the DL560C, known there as the WDM-2 (wide gauge, diesel, mixed use). More than 2 700 of this locomotive were produced, and they are still in service today.

Prime mover of the WDM-2 is the well known Alco 251-B, used on many of our domestic units of the day. Output of the locomotive is a decent 2 600 hp. The locomotive is geared to have a maximum speed of 75 mph in service. More details of the WDM-2 can be found on the Wikipedia page linked here.

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

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
