The Integral Coach Factory (ICF), Chennai has published a tender for supply of electrical equipment and other items for 44 train sets of 16 coaches each for the Vande Bharat train service.
The procurement process promotes transparency, accountability, speed of delivery, an official press release said.
It ensures compliance with RDSO specifications and vendor neutrality to allow maximum potential bidders to ensure competitive rates. It improves upon the passenger throughput by way of higher acceleration/ deceleration and reduction in turnaround time, the release said.
The revised specification takes care of the improvements pointed out by Chief Commissioner for Railway Safety in the prototype rake and will provide more reliable service along with ease of operations and improved passenger comfort, it said.
Prime Minister Narendra Modi had flagged off the maiden run of the Vande Bharat train on New Delhi-Varanasi route on February 15 this year. The second such train started service between New Delhi and Shri Mata Vaishnodevi Katra from October 3.
In order to improve upon the passenger throughput by way of higher acceleration/ deceleration and reduction in turnaround time, Indian Railways have planned to introduce passenger train sets with distributed powering, working on 25000 V single phase 50 Hz OHE system, the release said.
This project is driven by the corporate mission of providing semi high-speed trains with a service speed of 160 KMPH having a world-class technology and passenger amenities.
All coaches in the train set will be Chair Car type for day travel. All the train sets will be provided with fully air-conditioned passenger compartment with vestibule arrangement, automatic plug doors with retractable footsteps and automatic intercommunication doors.
It will also have coach displays, speakers, side destination boards etc, luggage racks with reading lamps, direct lighting (for passengers) and diffused lighting (for luggage racks) and continuous LED light fixtures.
There will be modular pantry equipment and GPS antenna in all coaches. The train will also have mobile/laptop charging sockets in the passenger seats, CCTVs and Emergency talkback units with networking system in all coaches.
The tender will be two packets single-stage bid, where the bidder has to submit electronic bids for the technical and financial bid simultaneously. The technical bid will be opened first and the offers found eligible will be categorised as qualified.
After evaluation of the technical and commercial suitability of offers for the placement of the order, the financial bid will be opened for technically suitable offers.
The revised specification takes care of the improvements pointed out by Chief Commissioner for Railway Safety in the prototype rake and will provide more reliable service along with ease of operations and improved passenger comfort, the release said.
"These lightweight energy-efficient trainsets will have a ride index of less than 3.5 against the earlier value of less than 4, which will improve passenger comfort even for longer journeys.
"These optimized trainsets will also be suitable for operations in Jammu and Kashmir and the electrics will be tested for continuous operations at 160 kmph," it said.
The new trainsets will provide an actual saving of 20% in journey time and all equipment is suitable for flooding conditions.
The interiors will have improved fire safety as per EN 45545 HL2 and improved electrical protection and safety with a well-defined protection scheme for high voltage roof cable, automatic fire detection and alarm.
The trainset is also provided with explosion-proof, lightweight lithium-iron-phosphate batteries specified to provide back up for the duration of three hours, state of the art aluminium body roof-mounted packaged unit (RMPU) type air-conditioning units with thermal comfort-based microprocessor controller.
The peak efficiency of the propulsion system of these trainsets will not be less than 87% which provides for a more robust, efficient and reliable system. These trainsets will be supplied in multiples of Basic Units of 4 coaches each which can be attached or detached from the train as per requirement.
"This will be a major improvement in reliability and operational efficiency as it will be possible to replace basic units in case of defects or augment the train length up to 24 coaches in case of increased demand. The present trainsets do not have this feature because of which the entire trainset is rendered ineffective in case of any defect in a coach," the release added
