RAILWAY STATION
Defination:
It is a place on a railway line, where trains are 1. Stopped for the passengers and freights to be entered or dropped and 2. An authority to proceed is given to the train.
TYPE OF STATIONS
There are three types of Railway Stations.
1. Way side Stations 2. Junction Stations 3. Terminal Stations
1.WAY SIDE STATIONS The station on which trains moves only in two direction i.e., upside & downside direction. These are further classified in to following three types.
a) Halt Stations b) Flag Stations c) Crossing Stations
1.WAY SIDE STATIONS Halt Stations: Simplest type of stopping place, usually with one Plate form. No permanent staff is kept. Flag Stations: In Flag stations only passengers & freight traffic is dealt, no arrangements to control the movement of trains and crossing facilities. It has building & staff facilities. Crossing Stations: They have facilities of crossing. There should be at least on loop line to allow another train if one train is standing on the track.
2. JUNCTION STATIONS Station where a branch line meets the main line are know as Junction Station. Necessary Arrangements at Junction •
Facilities for the interchange of traffic between main line and branch lines.
•
Facilities for repair and cleaning of the compartments terminated at junction stations.
•
Facilities for goods siding, engine sheds, turn table etc
3. TERMINAL STATIONS Stations at which a railway line or one of its branches terminates are called terminal stations. Necessary Arrangements at Terminal Station •
Facilities for servicing of engines.
•
Turn table for the change of direction of the engine.
•
Facilities for dealing goods traffic such as Marshalling yards, engine sheds, siding etc
TYPICAL RAILWAY STATION LAYOUT We can classify the typical layout of Railway Station into following two classes.
•
Building Layout (For users)
•
Layout of essential components of a railway station (For Engineers)
SIMPLEST LAYOUT OF A RAILWAY STATION
DETAILED LAYOUT OF A RAILWAY STATION
Building Layout (For users) It comprises of the following: 1. Access Road 2. Car Parking 3. Entrance 4. Ticket/Booking Counters 5. Information Centers 6. Waiting Areas 7. Cafeterias 8. Bookshops 9. Public Call Offices 10.Internet Café 11.Washrooms 12.Prayer Areas

LAYOUT ( FOR ENGINEERS)
LAYOUT ( FOR ENGINEERS)
1. PLATE FORM Plate forms are divided into two groups. 1.
Passengers Plate Form
2.
Goods Plate Form
PASSENGERS PLATE FORM
Generally about 300m length of a BG railway plate form is desirable.
The edge of the plate form from the center of the nearest track is kept 1.7m away for B.G, 1.39m for M.G and 1.2 for N.G.
It is a place from where the passengers entrain or detrain.
It is a loading place.
The minimum length of the plate form for all gauges should not be less than 180m.
ESSENTIALS FOR PASSENGERS PLATE FORM
The minimum length of a passenger plate form should not be less than 180m.
The minimum width of plate form should not be less than 3.67m and it should be paved fully.
The plate form should be covered at least for a length of 60m.
The ends of the high level plate form should be in the form of ramp with a maximum slope of 1:6.
The slope of plate form in its width should be of the order of 1 in 30.
For efficient and safe running of trains at night, adequate lighting arrangement should be there.
Height of Plate form On B.G generally three types of plate forms are provided.
a) b) c)
The rail leveled plate form. Low leveled plate form. High leveled plate form.
The rail leveled plate form. Its height is equal to the height of rail.
Low leveled plate form The height of such plate form is kept 45cm above rail level.
High leveled plate form Its height is kept 76cm to 85cm above the rail level.
GOODS PLATE FORM: To facilitate the goods handling, generally the height of goods plate form is kept up to the floor level of the wagon. On B.G it is kept 1.0 m above the rail level, while on M.G and N.G railways this height is kept as 70 cm and 60cm respectively. ESSENTIALS OF GOODS PLATE FORM:
Weighing arrangements should be provided.
Goods shed should be provided.
Proper drainage facilities are must.
Facilities for direct access from goods plate form to train and access road/rail.
YARDS A yard is defined as a system of tracks laid within definite limits for various purposes such as sorting of vehicles, making up trains etc. It is also used to control The movement by prescribed rules, regulations & signals. Types of Yard 1. 2. 3. 4.
