3.3 Deendayalu coaches
Deendayalu (LHB GS) coaches developed using GFRE & DGFRP panels instead of NFTC & LP sheets respectively. Other improved features of Antyodaya coaches are provided in these coaches.
3.4 AC 2Tier in AC 3Tier shell:
Design developed for LHB AC-2T coach using of LHB AC-3T Roof profile. These developments resulting 260mm more headroom for upper berths. First coach turned out in March, 2018 to Firozpur division, Northern Railway.
3.5 SMART coach
First smart coach of Indian railways [NCR -18155/C (LWACCN)] manufactured at MCF furnished with Passenger Information Coach Computing Unit (PICCU) with various amenities like PAPIS, CCTV surveillance, OBCMS (Onboard coach monitoring system ,Water level indicator, Control of HVAC parameters and digital destination board ,Wi-Fi & Infotainment ,automatic fire detection and alarm system has been turned out on June,2018. It has started giving its preliminary report and going to eliminate on line failure and will facilitate preventive to predictive maintenance and thus will result into saving in terms of reduced maintenance and less down time and thus proposed for regular adoption. With the introduction of diagnostic system and also regular fitment of fire detection and alarm system, it is possible by Indian Railways to adopt superior technology such as articulated bogie and tilting coach technology which will facilitate reduced forces and stresses on fixed infrastructure (track and bridges) and will improve comfort and reduce the journey time on existing infrastructure. In fact, this will be the least expensive option for the existing infrastructure.
Second Smart coach NR 182737 (LWACCN) has been flagged off by Hon’ble Prime Minister on 16 Dec’18.
SMART Power car:
First of its kind power car has been rolled out by MCF which has been developed with M/s Kirloskar in Nov’18.
3.6 Review of design tolerances
In order to improve accuracy and quality of product tolerances are reduced from ±14 mm to ±2 mm in Body shell, Under frame, sidewall & roof
3.7 PU based Wet on Wet application on exterior painting
In wet on wet painting system after application of surfacer wet on wet top coat applied. In this process; No primer application, reduced painting cycle time and 6 years warranty for gloss and colour retention. It results in improvement in painting system to achieve high production. The painting will be done as per specification no. MMDTS 18034 Rev-04 and complete cycle time for painting of coaches is about 30 Hrs.
3.8 LHB DSLR Coach
Modern Coach Factory (MCF) has rolled out its first LHB DSLR Coach on 11.01.2019.
This coach has under slung a 500 KVA Diesel Generator Set releasing space on board accommodating passengers and luggage. The coach has seating arrangement of 6 differently abled with a specially design lavatory keeping in mind the special requirement of these persons.
Besides this, the coach will accommodate 30 general passengers in a separate area with a dedicated lavatory.
The coach has also a luggage area with 4 ton capacity.
3.9 Projects in pipeline
3.9.1 Manufacture of DPRS (Distributed power Rolling stock) & Metro coaches:
Propulsion System for DPRS
It has been decided to procure propulsion system for DPRS ( with complete Knowhow) through store tender.
Scope covers “Design, Development, Manufacture ,Supply, Integration, Testing and Commissioning of complete propulsion system and other subsystems including electrics for BG AC DPRS (Operational speed 160 KMPH)”
Manufacturing of Metro Coaches at MCF
Kolkata SG Metro: 7x6= 42 coaches
3.9.2 Aluminium Body coaches
MCF is interested to manufacture Aluminium body coaches and a DPR for manufacture of 500 Aluminium body coaches per annum at MCF/RBL.was sent to Railway Board for sanction of additional infrastructure & TOT required for Aluminium car body fabrication at MCF. Railway Board has added the work “TOT for Design, Development. Manufacturing and testing of Aluminium Body passenger coaches” under umbrella work “Up gradation of critical work centre of workshops of Indian Railways”. Further process in this regard is in progress at MCF.
Aluminum has high strength to weight ratio, high resilience and inherent corrosion, reduce the energy consumption. Aluminium is one of the materials for light weight passenger coaches which has high potential to substitute steel used conventionally in passenger coaches.
Other advantages in Rail car body manufacture are low haulage cost resulting higher payload, better fuel efficiency & lower pollution level, reduced Axle load to increase speed of train, less wear and tear on the fixed infrastructure (i.e. Rails and fittings etc), less maintenance cost, Ease of manufacturing, easier to machine than the steel improving tool life, Modular interiors, Possibility of easily removing the components during the maintenance and retro fitment in future.
3.9.3 Modular seat and berths
To over-come the time consuming activity of replacement of Seats and Berths in a coach in service which requires it to be dismounted from the coach for replacing the cushion and stripping of upholstery Modular design concept of Seats and Berths has been developed. In this design complete set of Seats and Berths arrangement can be replaced without dismounting it from the coach. The integral and Modular Seats consisting of Upholstery & Cushion gets replaced without removing the Berth-frames from the coach.
3.9.4 Manufacturing of High Speed Bullet Train:
National High Speed Rail Corporation Limited (NHSRCL) has planned 18 rakes of High speed trains from Japan and remaining 6 rakes will be manufactured/assembled at MCF. The speed of these trains will be 300 + KMPH with most modern features in safety and comfort. MCF has proposed NHSRCL to get remaining 6 rakes manufactured/assembled at MCF as the part of Make in India and ToT (Transfer of Technology).
3.9.5 World class interiors
