Bigger, faster & slicker trains to connect cities

With rising demand for inter-city travel, railways is stepping up production of diesel electric multiple unit (Demu) trains with better interior design, increased capacity and more pulling power suitable for connecting smaller towns. An advanced version of such a train was flagged off on Monday at the Integral Coach Factory (ICF). The 10-coach train with 1,600HP engine is made for South Central Railway.

“The new stainless steel Demu can run faster and carry more people than conventional ones. We have given importance to aesthetics while designing the train. The interior is screw-less like the interior of Anubhuthi (a new premium coach railways is planning to introduce for high-end travellers). This shows that the factory is capable of making premium coaches,” said ICF general manager Abhay K Khanna.

Demu and mainline electric multiple units (Memu) are coaches with their own motor cars and are used for shuttle services in semi-urban and rural areas. There are more than 1,000 trains in service. These are slower than the 105kmph the new Demu can reach.

“ICF has made the three phase AC transmission Demu indigenously. There is demand for a few hundred such trains across the country because they do not need a locomotive,” said Railway Board member Keshav Chandra.

The coach factory will make one more such train this financial year and more than seven such trains are in the pipeline. The trains will be made Euro II emission compliant in the future. “We may upgrade electric multiple units (used in suburban trains) to three phase AC transmission with switching technology,” he said.

Research Development and Standards Organisation was part of the project since it was conceived six years ago. “The train will have emission rate of 147g per brake horse power hour as against the 155g in 1,400HP Demu,” said RDSO director general V Ramachandran.

ICF launched a self-propelled accident relief train that can travel at 155km per hour and has an operation table and post-operative ward for Bilaspur division. ICF plans to make 15 such trains this year as Indian Railways plans to station one accident relief train at 59 divisions.

ICF produced 1,620 coaches this year and surpassed its target by 19 coaches, a 7.2% increase over 2011-12. ICF is planning to make 75 LHB coaches this year.
