102 Multi Dimensional spring cleaning device at PP Yard/BIA

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.

105 Cleaning of breather plug to reduce wheel shelling in LHB Coaches

Wheel shelling on wheel tread is a common problem in LHB coaches. This primarily occurs due to partial brake binding. When the brakes are not fully released, some amount of skidding takes place which gives flat spots on wheel tread. If this phenomenon occurs repeatedly, it eventually leads to metal chip off, also known as wheel shelling. As a result, the coach is then marked sick on this account if the length & depth of shelling spot becomes 40 mm or more and 1.5 mm or more respectively. Subsequently, the wheel needs to be changed by detaching the coach from rake. This involves a lot of efforts and a significant cost.

During brake application and release process, air exhaust and intake takes place through a small part present in the brake cylinder integrated unit, known as ‘Breather plug’ (fig.1).During course of time, dust and other foreign particles deposit in the vent hole (fig.2). This obstructs the passage of air due to which brake application and releasing do not take place in a smooth manner, which eventually leads to intermittent skidding, thereby resulting in wheel shelling.

The breather plug was then cleaned properly and installed back (fig.3). This practice was started from 01.02.2018. The condition of wheel before cleaning of breather plug (fig.4, wheel shelling marks can be seen) and after cleaning of breather plug (fig.5, wheel shelling marks have considerably reduced) is shown below. The cleaning of breather plug helps in smooth brake application and releasing, thereby preventing wheel skidding.

106 Western commode with inbuilt ‘S’ trap and Cistern for better Flushing

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.

107 Natural forced ventilation in Bio Tank fitted toilets

Prior to fitment of Bio Tanks in coach toilet, natural ventilation was available through commode chute. During run, air enters and taken away all the foul smell generated due to defecation and urination. After fitment of bio tank, the problem of foul smell persisted and was a source of passenger complaint.

To overcome the problem of foul smell Natural forced ventilation system has been evolved using funnels. Two funnels have been provided in a coach facing forward and reverse directions each. Funnels are connected with coach toilet through pipes.

110 Gadget for bending of Air Brake Pipe

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.
