68 Introductory Handbook on Train-18

When one talks of trains in India, the image that strikes the mind is that of a locomotive hauling the coaches. Concept of Multi-Unit Distributed traction i.e. train-set is not heard in Indian Railways for Main line train operations. Even though Train-sets – Electric (EMUs) were running for almost a century and Diesel (DEMUs) were there since 1990s, for sub-urban services, the concept of train-sets for Main line intercity operations has not started . Advent of Metros in India has heralded a new era of Fully Air Conditioned Train-sets with Distributed Power System and introduced to the public the picture of Comfortable journey with aesthetics.

Train set is a set of rail coaches coupled mechanically and electrically with driving cabs at both ends and distributed traction power across the coaches. Depending on the requirement, the amount of power i.e. number of powered coaches can generally vary from 50% to 100%. In Train 18, 50% coaches are powered coaches i.e. motor coaches.
The distributed power train-sets have lighter axle loads, allowing operation on lighter tracks, where locomotives may be prohibitive of higher axle loads. Another side effect of this is reduced track wear, as traction forces can be provided through many axles, rather than just the four or six of a locomotive.

Train sets generally have rigid couplers instead of the flexible ones often used on locomotive-hauled trains. That means brakes/acceleration can be more quickly applied without an excessive amount of jerk experienced in passenger coaches.

77 Buffers Fitment in Coaches

Gadget for lifting of Side Buffers for fitment in coaches

Make: Developed at Coaching Depot, Santragachi, South Eastern Railway

Description:

            This rectangular shaped (120”x 14.5”) gadget (shown in picture below) is made up of SS pipes of  28 mm OD,1.5 mm thick with Sliding Table arrangement. This table is provided in such a way that the table with buffer can move freely on the longitudinal pipes of the gadget. There is a fixing arrangement at the ends of ‘A’ to be fixed with the bottom holes (2 nos.) on the head stock where the buffer to be fitted. Handles at the end ‘B’ have been provided for easy lifting of gadget manually. The gadget works as a Class 2 lever with fulcrum at end ‘A’ i.e. the head stock, effort at end ‘B’ and load (buffer) in between to achieve maximum Mechanical Advantage. Thus the gadget works successfully with less man power, time and ensuring safety.

Requirements for fitment of buffer:

i)   Gadget for lifting of Side Buffers for fitment in coaches developed at SRC

ii)  Box Spanner, Size 36

iii)  Manpower-3 persons to be provided

iv)  Wooden Skids- 4 nos.

 

Procedure for fitment of buffer:

          Before fitment of buffer in a coach, ensure protection of lines and provide skids on

the lines to avoid rolling of wheels of the coach. Steps for fitment of buffer are mentioned as under:

Step-1

End ‘A’ of the gadget to be fixed on the bottom holes (2 nos.) on the head stock where the buffer to be fitted .

Step-2

Fix buffer on Sliding Table provided on the gadget

Step-3

Push the table manually from end ‘B’’ to end ‘A’

Step-4

Simultaneously end ‘B’ of the Gadget is to be  lifted gradually with the help of handles provided.

Step-5

Place the buffer on the head stock and fix two upper Nylock nut bolts provided in the head stock to hold the buffer securely.

Step-6

Release the gadget

Step-7

Fix the lower two Nylock nut bolts. Ensure proper tightness of all  Nylock nut bolts.

 

Benefit:
  1.  The gadget is simple and portable.
  2.  Fitment of buffer is easy because of its mechanical advantage always more than 1.
  3.  Only 3 staffs instead of 9 staffs earlier are required for fitment of buffer.
  4.  Fitment time is also very less. 3 staffs can easily fit a buffer within 10 minutes.
  5.  It is very safe as there is no chance of dropping of buffer during fitment.
