Kapurthala, 29.05.2023:RCF has developed and manufactured Narrow Gauge coaches for Kalka-Shimla Railway which were unveiled today by Ashesh Agrawal, GM/RCF. These coaches will be transported to Kalka for second phase of extensive oscillation trials.Based on outcome of the trial, they will be planned to be put into service on Kalka Shimla route.
The prototype coaches made for the trial of four coaches include each of AC Executive Chair Car, AC Chair Car, Non AC Chair Car and a Luggage Car .
RCF was entrusted with the project to design and manufacture a new narrow gauge rolling stock for Kalka-Shimla Railway (KSR). This project posed significant challenges for RCF as there was no digital data for modelling of narrow-gauge tracks for development and verification of coach designs which developed around 1908. Notwithstanding the above limitations, the RCF Design team worked tirelessly to recreate the required design inputs using the experience garnered over years of developing rolling stock designs for IR Broad Gauge system. 3D models were created by RCF Design team by using the old blue print and sketches available at Kalka workshop.These models were then used as the baseline for development of the new designs for modification of the bogies and development of all new shell superstructure and furnishing designs.
After the Railway Board gave the design approvals, two prototype shells of Air-conditioned Chair Car and Luggage Car were manufactured in September 2022 which were rigorously tested by RDSO in October 2022 for static stress analysis at RCF. In December 2022, these 2 semi-furnished shells were transported by road to Kalka workshop and tested on Kalka Shimla route at speeds higher than the present sectional speed to determine the stability and ride quality. After successfully testing the shells under static and dynamic conditions, RCF developed the interiors suiting the new design. The prototypes of these fully furnished AC Executive Chair Car, AC Chair Car, Non-AC Chair Car and Luggage Car have been unveiled today and will be transported to Kalka for extensive oscillation trials of second phase.
RCF will be manufacturing 30 such state-of-the-art narrow gauge panoramic coaches including 04 AC Executive Chair Cars (12-seater), 08 AC Chair Cars (24 seater), 13 Non-AC Chair Cars (30 seater) and 05 Luggage Cars. These coaches have a light weight shell with upgraded bogies and improved air brake system. These coaches will have power windows and darkening vista glass in upper classes, Slide window in second class for panoramic wider view so that the passengers can experience the beauty of the mountains and valleys.
The coaches will also be equipped with modern safety features like CCTVs and fire alarms, Anti UV coated window glasses, Powered doors,Heating/coolingpackage AC, Linear concealed fans, Linear LED lights, Modular seating rail mounted seats with flip backs, restaurant type seating with luxury seats for Executive class, onboard Mini pantry, Luggage Bins, Inter-car gangway (Vestibule) etc.
Each train of new design panoramic coaches will consist of seven coaches – one AC Executive Chair Car, two AC Chair Cars, three Non-AC Chair Cars and oneLuggage Car.
