About – WDG4G Locomotive

Many of us in the rail fan community might be thinking – what are the features and specs of the locomotive. So let’s find it out. Nomenclature: W  – Wide/Broad Gauge D  – Diesel Powered G  – Goods load 4  – Class Type G  – GE (Manufacturer) The ES43ACmi (Indian Railways’ class – WDG4G) locomotive, painted in a distinctive red and yellow pattern, is the first of 1,000 diesel freight locomotives that GE Transportation will deliver to Indian Railways as part of a $2.5 billion order. The bright colors hold special meaning in India with red representing energy and yellow representing freshness. Before the mass production of locomotives at Marhowara (Bihar) few locomotives are been produced and tested in USA. This project comes under the  Make in India  initiative. The ES43ACmi( WDG4G ) locomotive is one of two models GE Transportation is building for Indian Railways as part of the order. It’s a dual-cab locomotive with a 4,500-horsepower eng...

Maglev – Introduction.

By -

Maglev (derived from Magnetic levitation)  is a transport method that uses magnetic levitation to move vehicles without making contact with the ground. Maglev trains does not have any wheels they move in air due to the magnetic repultions. Maglev trains move more smoothly and more quietly than wheeled mass transit systems. The power needed for levitation is typically not a large percentage of its overall energy consumption; most goes to overcome drag, as with other high-speed transport. Compared to conventional trains the maglev trains are costly to establish but saves more after.Moreover such high speeds are possible to get only through a non frictional model. The most energy generated in a normal train (may it be generated by diesel or by electricity) is wasted by the forces which oppose the motion among which the frictional force is a major factor. The non contact feature of maglev reduces the energy loss to a great proportion due t...

About – Trainsets

In India we are familiar to only on system of trains that is a locomotive leading the coaches (I say it as  leading power system ). This system is neither safe,fast nor efficient. For the replacement of these few countries have introduced  Trainset System.  Trainset system train used in paris. What are Trainsets? Trainsets are just coaches having their own traction motors for each pair of wheels which are controlled by a controller system present in the first and/or last coach in the set. Why they are fast? It is quite simple to answer this. The individual traction motors makes the power distribution good so the momentum transfer from locomotive to coaches is not required hence the speed becomes good. Other features Good Acceleration :  Because they have individual traction motors they are good in acceleration. Safer than leading power system :  The change in momentum is negligible when train stops or starts so there is low probability of ...
