Indian Railway Seat Allotment System (in detail)

Indian Railway Seat Allotment System

Indian Railway Seat Allotment System And Criteria’s

Indian Railway Seat Allotment is dependent on the following 3 things:

1] Train type

2] Serial/ Non-serial

3] Journey type.

Let’s begin with the first one;

IRCTC Train Timings and Seat Availability

1] Train Type

There are 2 types of trains in the PRS

A] End To End Train

The trains that likely travel from the Source to Destination which has no or very less intermediate stations are called end to end trains. Normally these trains run between long distance stations where there is a huge demand for them.

B] Non-End To End Train

These are normal trains that halt on many intermediate stations during their journey. Passengers on these trains do not need to travel long distances.

Allocation In These Trains

I] Some of the long distance trains are earmarked as “End-to-End” trains. The main goal of these trains is to take care of the passengers that want to travel for long distances. Such passengers travelling for that long range are booked against End-to-End quota.

II] Passengers those who do not want to travel for such long distances are booked against pooled quota.

III] Very few seats are available in pooled quota. Once these seats are full, then the short-distance passengers go in pooled quota waiting list even when the general quota is available.

How The Partially Vacant Berths Are Utilized

I] Such vacant berths can be utilized only against pooled or general quota.

II] These vacant berths are given a priority over fully vacant berths when a transaction is made of normal reservation.

III] Partially vacant berths are allowed to be booked even when source waiting list has already begun.

IV] When a large number of seats are being booked at an instance, then end to end berths are given priority over partially vacant berths.

New Rules For Maximum Utilization Of Accommodations

  1. Even if end-to-end waiting list has already begun, partially vacant general source and pooled quota berths can be booked.
  2. Once the remote quota is full, the system will start utilizing partially vacant general and pooled quota berths.
  3. Tatkal waiting list tickets can be issued from the counters. They can also be issued against remote tatkal and roadside quota.
  4. A new quota called “SS” has been introduced that has some lower berths reserved for senior citizen/woman above age 45 or pregnant woman travelling alone.
  5. Such booking has to be done using form number 2. If the above-mentioned conditions satisfy then SS quota requested is passed and seat allocation is being done.
  6. SS quota behaves similarly to Ladies quota, which means that once SS quota berths are full then the system will start issuing berths from the general quota as per normal guidelines.

2] Serial/ Non-serial Allocation

A] Serial Allocation

  1. AC 1-tier, First Class berths are allocated serially.
  2. At the time of reservation, no particular seat will be allocated to the passengers. Instead, the passengers will be notified if they will get a confirmed seat or will go into the waiting list.
  3. Berths/Seats will be allocated to the passengers at the time of chart preparation.
  4. This way, it is made sure that couple/cabin requirements of VIPs are taken care of.
  5. After such requirements are fulfilled, the railway staff allocates the berths/seats to the passengers serially.
  6. Therefore, at the time of reservation, the passenger will only get the status of confirmed/ RAC/ Waitlist tickets.

B] Non-serial Allocation

  1. AC 2-tier, AC 3-tier, AC Chair Car, Sleeper Class and Second Class are allocated non-serially.
  2. Berths/Seats are allocated to the passengers on the basis of the following criteria’s:
  3. Coach selection criteria
  4. Berths/Seats Selection criteria.
  5. Passenger preference and
  6. Compact accommodation

Non-Serial: Normal Transaction

  1. When the passenger applies for a reservation, all the details of that traction i.e. source, destination, and quota are taken into consideration.
  2. The coaches that meet all of these requirements are then sorted in ascending order of availability of accommodation.
  3. The first applicable coach is scanned to see if the passenger preferences can be met.
  4. The search starts from the middle of the coach.
  5. When such a cabin is found, then it is selected otherwise the next coach is scanned in the same fashion and so on.
  6. When all the criteria’s and preferences are met by a cabin, berths/seats are allocated accordingly taking into consideration old people and Women.
  7. Therefore, compaction is given a priority over the choice.
  8. If no single cabin satisfies the requirement, then the transaction is split over a minimum number of cabins.
  9. Similarly, if no single coach satisfies the requirement, then the transaction is split over the least number of coaches which on combining can satisfy the requirement.
  10. If the requirements cannot be met fully or partially, then some or all of the passengers will go to RAC or the waiting list.

3] Journey Type

Journey type comprises of 3 types of transactions as given below:

A] Direct Transaction

For a non end-to-end train, a direct transaction is the one which has the starting station that lies on the first leg of the journey and before the 1st station which has a roadside quota and it ends at a station that lies after the last station of roadside quota.

For end-to-end train, a direct transaction is the one in which the journey’s starting station which in the first “end to end definition” range and the destination station lies in second “end to end to definition” range.

This reservation module will provide accommodation to the direct passenger against general quota. If there is no accommodation left, then the passenger will be put into RAC/Waitlist.

B] Non-Direct Transaction

This type of transaction is not a direct one. It originates from a station while is prior to the second remote location. The first remote location of a train is considered as the source station.

The order of scanning is strictly maintained and compact accommodation is ensured to the extent of single coach only which achieves the purpose of efficient utilization.

C] Remote Transaction

This is the transaction that is not a direct transaction and originates either from the second remote location or from a station which lies after the second remote location, in the case of non end-to-end train.

Whereas, in the case of end-to-end trains, this is a transaction that is not a direct transaction and originates either from the second remote location or from a station which lies prior to the second remote location.

I love to travel and I prefer trains for the most part as it is an inexpensive way to travel along our huge country. There are lots of problems that I go through and I share my experience with others to keep them well informed.
