A WDS-6 locomotive basically consists of a YDM-4 powerpack (a 6-cylinder, 4-stroke, inline, turbo-supercharged ALCo engine) mounted on a WDM-2 body frame. Beginning in 1975, these were initially manufactured solely by BLW, Varanasi , but later, the Parel Workshop started building them using CKD (completely-knocked-down) kits provided by DLW.
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads.Essentially a simplification of the European UIC classification, it is widely used in North America to describe diesel and electric locomotives (including third-rail electric locomotives).
This was the first model of any locomotive series to be fitted with microprocessor-equipped engine control units. A total of 581 examples of the model were manufactured between 1987 and 1992. The C40-8 has a traditional narrow short hood, but otherwise its external appearance is almost the same as that of the later Dash 8-40CW model.
The Western Electric rules are decision rules in statistical process control for detecting out-of-control or non-random conditions on control charts. [1] Locations of the observations relative to the control chart control limits (typically at ±3 standard deviations) and centerline indicate whether the process in question should be investigated for assignable causes.
The ALCO S-2 and S-4 are 1,000-horsepower (746 kW) diesel electric switcher locomotives produced by ALCO and Canadian licensee Montreal Locomotive Works (MLW). [1] Powered by turbocharged, 6-cylinder ALCO 539 diesel engines, the two locomotives differed mainly in their trucks: the S-2 had ALCO "Blunt" trucks; the S-4, AAR type A switcher trucks ...
They were built under the same premise that a lower power rating than the 4,400 hp (3,300 kW) rating of the Dash 9-44CW (or C44-9W) (see below) would prolong the life of the engine, and use less fuel. However, there is a manual override switch that allows the engineer to run the engine with all 4,400 hp (3,300 kW) if necessary.
The Indian locomotive class WDG-4G (GE ES43ACmi) [1] is a class of dual-cabin freight-hauling diesel–electric locomotive used by the Indian Railways (IR). The locomotive is designed by GE Transportation and is based on its Evolution Series, which are used in North America.
The Detroit Diesel Series 60 is an inline-six 4 stroke diesel engine produced from 1987 to 2011. At that time, it differed from most on-highway engines by using an overhead camshaft and "drive by wire" electronic control. In 1993, it was popular on many USA buses in the 11.1 L (677 cu in) displacement.
