India's 1st Standard Gauge takes Delhi Metro to Mundka
first i like to tell that mumbai suburban train are either 12 cars (mostly) or 9 cars rake. we have only one 15 car rakes running on western railway that too on experiment basis so train of 18 car rake is out of question plus it doesn`t run regularlyMumbai local trains to get cosier
The Mumbai rail journey has been synonymous with profusely sweating passengers struggling to find a footing, stepping on others' feet, travelling on footboards, rooftops and connecting bumpers, besides latching on to the windows. This means great discomfort and huge risk.
Now, Lucknow's Research Design and Standards Organisation (RDSO) — the sole R&D wing of the Indian Railways — is all set to help better the scene. The Research Design and Standards Organisation on Thursday inked a multi-crore MoU with Mumbai Railway Vikas Corporation (MRVC) to considerably improve the quality of journey on board trains there. This comes as a major boost to the Research Design and Standards Organisation itself especially with major research work being shifted to West Bengal and its relevance being questioned in the wake of failure of safety projects leading to back-to-back accidents. "For the common passenger, we're going to up the trains speed up to 110 kmph, increase the number of coaches per train from the existing 12 to 18 for load-shedding, introduce a better ventilation system and ensure a smooth ride by controlling jerks," said AK Mathur, RDSO's Executive Director (Admn & PR).

hi tarunraju thanks for providing the information. its too bad that India having second largest railway network imports railway engine and kills local product .what are railway minister doing?second i want ask is Pushpak is being used in large numbers. third why donot railway minister start a separate research,design+manufacture unit that will concentrate on exporting railway related stuffs to world this would bring good money to railways and improve its health. look china its exporting railway locomotives , equipments to most countries in worldBut then the Pushpak team hit back with the WDM3D which took the GM loco's best design features and bettered them. WDM3D = board gauge diesel-electric mixed-use 3000~3999 HP class. It returns to the traditional ALCO DM single-cab chassis, but uses the same 3300 HP engine, advanced computer control, desk-type cabin, fuel-efficiency, and other features that make it a better option for Railway zones than WDP/G4.

Here's the WDP4 "Baaz":
Loco pilots simply call it P4.
1. The WDP4 and WDG4 were imported because the railways found that running two 4000 HP engines gave nearly the same hauling power as three 3000 HP engines, while being much more fuel-efficient (2 units vs. 3). In Triple WDG3A, the three engines also end up hauling their own weight (called "dead-weight"), and in the process their efficiency goes down. Further, with increases in air-conditioned coaches per express service, a single WDM3A engine isn't sufficing in 21-coach rakes. An AC coach adds more load to the engine because each coach has its own alternators. IR got over this with powerful electric engines such as the 5000 HP WAP4 and WAM4-P, but in routes that are not electrified, they were having to use two WDM3A engines (fuel-efficiency takes a beating, especially when just a few more hundred HP is required). WDP3 was able to solve the problem, but wasn't able to offer 'future-proofing', if railways decides to further increase the number of AC 3-tier coaches per service (Indian middle-classes are increasingly able to afford travelling by AC 3-tier). Hence WDP4 came to be. Ironically, the same IR decided that the 3300 HP engine is much more fuel-efficient for most services, and invested in the development of WDM3D (picture above the WDP4). The second solution which is implemented on trains such as Rajdhani Express (which have 100% AC coaches) is that it has a dedicated Generator Van, which houses powerful diesel generators, while being hauled by a simple WDM3A. In such rakes, the coaches lack their own power-plants, and draw power from the generator van. Fuel-efficiency is a problem then. IR is limiting this approach to Rajdhani services.hi tarunraju thanks for providing the information. its too bad that India having second largest railway network imports railway engine and kills local product .what are railway minister doing?second i want ask is Pushpak is being used in large numbers. third why donot railway minister start a separate research,design+manufacture unit that will concentrate on exporting railway related stuffs to world this would bring good money to railways and improve its health. look china its exporting railway locomotives , equipments to most countries in world
