In regular practice coil springs used in Bogie are being cleaned manually. During manual cleaning it is observed that dust particles are spread in the nearby area, which is not desirable. In addition to the above, carrying of spring from the dismntling area to the cleaning bench is also a laborious job.

To get rid of the above a “Multi dimensional spring cleaning device” has been made with the available resources. A rejected unserviceable conveyor system has been used by providing motorized reduction gear box with chain sprocket system. It’s two sides are having protecting wings for safety purpose and four types of brushing arrangements provided for cleaning of springs in different ways.

No new items used. Only scrap & unserviceable relevant items used. Hence total direct cost is Nil. Indirect cost for scrap value is Rs.10,000/- approximately  & cost of man power is Rs.8000/- approximately.

The following practices are being done during the corrosion attention of passenger coaches

1. Leveling of coach on trestles is being done for checking / measuring the camber loss and twist in bolsters.
2. Staggering of sole bar joints.
3. Staggering of  End Body pillar joints.
4. Minimum length of sole bar has been restricted to 1200mm.
5. Compulsory renewal of sole bars while headstock attention upto a length of 2700mm and 2500mm on either sides.
6. Additional strengthening of sole bar joints by providing  strengthening plate.
7. Thorough checking for cracks done after opening the side panel on sole bars near the bolsters.
8. Ensuring proper headstock alignment by inspecting headstock with water level according to the required camber and verticality of Outer Headstock with spirit level.
9. Provision of drain holes in turn under near doorway pillars in order to avoid accumulation of water and dust.
10. High performance epoxy painting of components done.
11. Ensuring proper edge preparations.
12. IS 9606 Qualified Welders are engaged in welding.
13. Welding consumables are procured from RDSO approved vendors
14. ISO 3834 qualified welding process.

     

Flush cock provided in the coach toilet is very hard to operate and is located at inconvenient location. This creates reluctance amongst passengers to use it. As a result faecal discharge remains in the pan and causes bad odour in the coach toilet.

To get rid of these problems the existing conventional western commode      replaced with  western commode inbuilt ‘S’ trap and Cistern for better flushing in three 1st AC coaches of train no. 18239/40 Shivnath Express on trial basis. Inbuilt S trap ensures smooth passage and establishes siphoning action. This is assisted by sudden discharge of limited quantity of water from Cistern (around 06 litres per flush), thus water efficient flushing. This also solve the problem of bad odour up to maximum possible extent by ensuring proper water column.

Two lavatories and two urinals were in abandoned condition in Coaching Depot, Bilaspur and the need of functional toilets was experienced several times for staff convenience as a welfare measure. However, that was requiring the complete dismantling of existing structure and rebuilding of new one along with connection to septic tank. Also the use of this existing toilet is unhygienic due to its outlet was open in atmosphere. The modification done by connecting the outlet of existing toilet with the serviceable biotank available in Coaching Depot by using 150 mm dia PVC pipe. Thus the problem of open discharge of defecation gets solved by biologically efficient way.

A gadget for bending of Air Brake Pipes was developed by a group of staff of Air Brake Section in the month of March’18 by utilizing one serviceable brake cylinder and some other scrap materials. It works with the aid of compressed air. The bending work carried out in cold condition of pipes. Due to cold bending grain structure of material do not changes as well as no stress develops. Desired angle of bend and finished are also achieved.

Bogie section of Motibagh workshop has manufactured one fixture for cleaning and painting of lower spring beam . It rotates at 360 degree resulting easy for painting and welding. Also improve the quality and save time for repairing and painting.

CTRB section of Wheel shop was developed and declared as a Centre of Excellence on 27/11/2017. Various resources available in the section are as follows,

1. For cleaning, The following machines are being used.

a) Grease purging machine b) Grease loosening machine and c) Cone cleaning machine

2. An air plug gauge (Make: Baker) is being used in Wheel shop which helps in measuring the diameter of double cup /cone assembly in CTRB bearings. This gauge can measure upto 0.1 micron and the tested data can be stored and retrieved from the system for reference.

3. Bore diameter of the cone is being measured using three legged digital micrometer. In order to measure other dimensions, seperate gauges are available which are being calibrated using a master gauge on regular basis.

4. Seperate storage area is available for storing various components of the CTRB bearing.

5. Laser engraving machine is being used for entering the details on CTRB bearing instead of manual etching process.

6. Automatic grease filling machine is being used after inspection instead of manual process.

In addition to above machineries and gauges, the following works have been carried out to develop this section as a 'Centre of Excellence'

a) Wheel Exhibit has been displayed showcasing the different set of wheels used in Indian Railways thereby preserving the Heritage assets.

b) Epoxy flooring has been provided in the CTRB section in order to ensure a clean workplace.

c) Wall panelling using compreg sheet, false ceiling facilities have been made as per RDSO checklist.

d) In order to achieve Energy efficiency, LED lights and natural pipe lighting arrangments have been made. Enegy efficient air conditioner is being used.
