10 unknown interesting facts about Central, Western line of the Mumbai Suburban Railway:



Western Railway:

1. In its present form, Western Railway came into existence on November 5, 1951 by the merger of its forerunner, the erstwhile Bombay, Baroda and Central India Railway (BB&CI), with other State Railways viz, Saurashtra, Rajputana and Jaipur.

2. The BB&CI Railway was inaugurated in 1855, starting with the construction of a 29 mile broad gauge track from Ankleshwar to Utran in Gujarat state on the West Coast with Surat as its headquarters then.

3. On November 21, 1855 the Company concluded an agreement with the East India Company to construct a railway line from Surat to Baroda and Ahmedabad. Another contract was signed to start a line from Utran (north of Surat) to Bombay to ensure a plentiful supply of cotton grown in Gujarat coming into the western port. Work commenced on the line in the following year and the line from Uttran to Grant Road station in Bombay was officially opened on November 28, 1864 – marking the beginnings of the Western line. The process of the actual founding of the BB&CI local line to and within the city of Bombay and the identification of a terminus, particularly south of Grant Road – the first terminus, was a perplexing issue.

4. Although the inaugural run terminated at Grant Road station, this terminus did not adequately serve the population which lived further south; near the old Fort or the cantonment at Colaba that was now serving a sizable population. It was decided to extend to the Back Bay, just outside the western side of the old Fort area and alongside the western bay. This station was subsequently called Churchgate as it was in close proximity to the old Church Gate of the fortified town – the gate that afforded entry to St. Thomas Church that later became a Cathedral.

5. Western Railway has grown with the city of Mumbai and Mumbai city has grown with Western Railway and has been the cynosure of the development of the city of Mumbai. The Mumbai Suburban System of Western Railway exists from Churchgate to Dahanu Road. The present jurisdiction of Western Railway is in 6 divisions i.e., Mumbai Central, Vadodara, Ahmedabad, Rajkot, Bhavnagar and Ratlam.



Central Railway:

1. The first train in Asia (and India) ran between Mumbai and Thane on Saturday, April 16, 1853 at 3:35pm. The day was declared a public holiday. Bori Bunder, the point of departure was thronged by a multitude, and bands played and guns were fired from the Fort's ramparts, when at the signalled moment, there steamed out from a tiny wooden station, the little train hauled by three engines that heralded the dawn of the Railway Era in India.

2. As the years passed, the Great Indian Peninsula Railway expanded. With the merger of the Indian Midland Railway Company with the G.I.P. Railway Company in 1900, its frontiers were extended from Delhi in the North, Kanpur and Allahabad in the North-east and Nagpur in the East to Raichur in the South-east. Thus, through connection from Bombay was obtained to almost all parts of India. The route mileage of the G.I.P. Railway was 1,600. (2575 km)

3. On November 5, 1951 Central Railway was formed by integrating Nizam State, Scindia State and Dholpur State Railways, with GIP Railway. Central Railway suburban railway network has played a pioneering role in socio-economic growth of the city of Mumbai and also heralded the advent of mass rapid transit system in India. Central Railway has come a long way since then and now it has a vast network of 4151.93 route km traversing through the states of Maharashtra, Madhya Pradesh and Karnataka. Mumbai Suburban Network of Central Railway is one of the largest networks in the world carrying approx. 4.5 million passengers every day.

4. In October 1966, one more railway viz. South Central Railway was formed by merging Solapur Division from CR and Secunderabad, Hubballi, Vijayawada Divisions from SR. On 2nd October 1977, Solapur Division was merged with CR and Guntakal Division from SR was included in South Central Railway.

5. Later in 2003, seven more zones were created wherein, Jabalpur and Bhopal Divisions of Central Railway were included in West Central Railway and Jhansi Division was included in North Central Railway. As on date, CR has 5 divisions viz. Mumbai, Bhusaval, Nagpur, Solapur, Pune with a network of 466 stations.

Ques) What is "Chart Not Prepared" status?

Ans) The last booking chart for a train will be done at least 4 hrs prior to the schedule departure of the train at originating station.
But in reality, charts have been getting prepared 1 or 2 hrs prior to the actual departure of the train.
In

situation of early morning or late evening trains, this might be prepared considerably earlier during the previous night itself.
A person's booking standing might change any time till chart is prepared.
Though quite uncommon, it is possible that an RAC ticket can change to wait-listed status.
It is also possible that booking relocated from WL to CNF can return to RAC or WL.
However none of this will certainly not happen for a ticket which was CNF while Booking itself.

Types of Station in Indian Railways
Based on Function stations may be classified as follows : -
1. Way Side station
2.Junctions
3.Terminals
...
more...

1. Way Side Stations
It is a station set between principle stations on a line of travel where the train stops only on a signal. It is an intermediate stopping place. It is a common type of station where some trains stop and some do not. The train coming in opposite direction are accomodated. Loop lines and sidings are provided in such stations to facilitate faster trains to overtake a slower train. Platform in sufficient number are provided for up and down trains as well as for goods trains. Sidings help in sorting the goods wagon. Picture 1 given below is the picture of a wayside station. The wayside stations without sidings or loop lines are most often referred to as 'stops' or 'halts'.

2. Junction Station
A station where a branch line meets the main line or a main line of different route meets the main line of another route is called a Junction. Therefore Junction has facilities for interchange of traffic from one line to another line. Figure 2 given below ithe picture of Junction station.

3. Terminal Station
A station where main or branch line terminates is called a Terminal Station. These stations have facilities for passengers stay and repair of rolling stock , facilities for reversing the engines , number of sidings and examination pits. Hydraulic buffers are provided but they are meant as last resort to stop an engine when drivers effort to stop it fails. These are provided at the end of tracks. Terminals have enough circulating areas , ticket offices , passenger ammenities like retiring rooms and restaurants and goods storage sheds. Figure 3 is a picture showing a terminal station.

Screens Details
1. SCREENS
The Driver display has pre-defined dedicated screens in order to monitor real time process variables pertaining to a particular section or sub-system of the locomotive. However, such screens are meant for online monitoring by technical staff whenever required. The locomotive driver, however, needs to view the default screen only most of the times. The screens have been designed to take care of the specification requirement. The details of the screens are explained below.


2. SUB-SYSTEM STATUS
In the sub-system status menu, the names of the sub-systems are listed. To navigate to default screen, press "HOME". To navigate to list of screens, press . The isolated sub-system will be shown in red.


3. HIGH VOLTAGE CIRCUIT
In the high voltage circuit screen, Harmonic Filter status and Hotel Load status are additionally provided. Other variables are already available in the default screen. Hotel Load facility is available only in WAP7 & WAP5 class of locomotives.


4. I/O SIGNALS
The physical input/output signals, both analog and digital, can be viewed using this multi-level screen. In this screen, the description of the signal, name used in FUPLA and the location of the signals and the actual value can be viewed (channel+slot+connector+pin number eg: 12/EA05 : means channel-12, E slot, A connector, pin-5). These screens will be quite useful for troubleshooting.


5. TRACTION CONVERTER
In traction converter screen, converter related parameters are displayed. The screen is split into two columns, one for each traction converter. The process variables displayed include pre-charge & input contactor status, oil pressure & temperatures, input power & ventilation level. Other displayed parameters are already available on default screen.


6. AUXILIARY CONVERTER
The Auxiliary Converter screen provides very vital process variable display about the BUR, which will help in easy trouble shooting. The variables include Auxiliary winding voltage, Total current in the auxiliary winding, dc link voltage & dc link current of each BUR, output voltage and output frequency. Please note that there is no direct signal available for the output voltage whereas the displayed value is calculated from dc link voltage and output frequency considering constant v/f relation. The screen also provides the status of BUR grouping contactors.


7. TRACTION MOTOR
The traction motor screen is also vertically split into two columns, one for 3 motors belonging to one bogie. The relevant process variables like input contactor status, dc link voltage, ventilation level, converter input power, wheel slip status, speed of each traction motor reported from speed sensor and temperature of each traction motor reported by the temperature sensor are displayed.


8. AUXILIARY SYSTEM
The auxiliary system screen essentially displays the status of various auxiliary machines, as to whether these are OFF or ON. It also indicates the BUR status and BUR input volatge. The auxiliary machines considered are Compressors (1,2), Oil Cooling Blowers (1,2), Oil Pump Converter (1,2), Oil Pump Transformer (1,2), Traction Motor Blower (1,2) & Machine Room Blower (1,2).


9. BRAKING SYSTEM
The braking system screen displays the process variables related to braking, which include locomotive speed, master controller position (traction/braking region), BE demand and BE Actual, Pneumatic Brake Effort demand (when regeneration fails), regenerated power & energy as well as status of compressor.


10. ENERGY MONITORING
The screen for energy monitoring displays the energy consumed and regenerated. The cumulative value is the one taken from the NVRAM of DIA computer, which is available on MVB. The trip energy is calculated by the driver display itself from the time of switching ON. This value is not saved in any memory and will vanish once the locomotive is OFF. Trip energy can be used for comparison of driver performance under identical conditions of operation.
The regeneration ratio (energy regenerated/energy consumed) is calculated by the driver display and displayed. This factor also provides a measure of the efficiency of regeneration and is a good comparison tool.


11. TEMPERATURES
The temperature screen provides various temperatures recorded by sensors and the same can be compared with the converter input power. The temperatures of transformer oil, traction converter oil and traction motors are displayed alongwith converter input power for each bogie.


12. PRESSURES
This screen shows the pressure variables. It include Transformer oil pressure, converter oil pressure, MR pressure, BP pressure and status of BC1 & BC2.

Understanding your ticket and WL number of PNR status
On Railway ticket, there are two numbers which tell the position at which you joined the waitlist and current position.
Example:
You have booked a Railway Ticket to some destination.
At
...
more...
the end of the Booking Ticket, you get a ticket with Position as WL5/WL2.
In this example you joined the waitlist at position 5 (WL5), but by the time you actually bought the ticket online you moved to waitlist position 2 (WL2) (due either to a cancellation or to someone not making a final booking).
The first number (WL5) will always stay the same � it indicates position you joined the queue.
The second number (WL2) will decrease until you get a ticket.
Your railway reservation could change / upgrade like:
WL 5/WL 2 (Starting Position . Waitlist 2)
WL 5/WL 1 (Waitlist 1)
WL 5/RAC 3 (Reservation Against Cancellation 3)
WL 5/RAC 1 (Reservation Against Cancellation 1)
WL 5/CNF (Seat Confirmed)
AB1 (Seat Number Confirmed)
WL 5/WL 2 = Waitlist ticket : you cannot board the train.
WL 5/RAC 3 = RAC ticket : you are allowed to board the train, but you may end up on a seat instead of a berth.
WL 5/CNF = Confirmed ticket : you can board the train and you have a berth to yourself.
