RRTS is a brand-new mode of public transportation designed specifically for NCR. It is a rail-based, semi-high-speed, and higher-frequency commuter transit system.

Unlike conventional trains, RRTS trains will travel at a high speed, reduce road congestion, and carry many passengers. The high-frequency operations of the RRTS trains ensure the arrival of trains every 15 minutes. As it encourages more people to travel via public transport, it will help to reduce air pollution and work towards sustainability. 

Telangana government recommended taking up the Regional Rapid Transit System (RRTS) in two corridors: Hyderabad-Warangal and Hyderabad-Vijayawada. The RRTS project was initiated after the successful operations of Hyderabad Metro Rail Limited (HMRL).

The reason behind the state government’s plan to impose two RRTS corridors in Hyderabad is to reduce the fluctuation of passengers on these two corridors.

Project Approval and Cost

The Hyderabad-Vijayawada RRTS Project would require inter-ministerial consultation and approval due to the high costs involved in the construction of the RRTS. The approvals depend on the feasibility of the projects and the availability of resources. The construction work and allotment of funds for the project will be undertaken once the project is approved.

The Telangana government will establish a transport corporation similar to the National Capital Region Transport Corporation (NCRTC). The corporation would take up the RRTS project and obtain funding from the central government.

Railway platforms

A railway platform is is a designated area adjacent to the railway tracks. Railway platforms are designed to provide easy and convenient access to trains. Most rail stations feature multiple platforms, with larger stations having several to accommodate different train services. The world’s longest station platform is at Hubballi Junction in India. It is 1,507 metres (4,944 ft) long. 

Types of railway platform

1.Bay Platform

A bay platform is a type of railway platform where the track terminates in a dead end. Trains serving at the bay platform have to reverse in or out. The bay platforms are often used when reverse action for the trains is required. Due to their design, bay platforms require additional space compared to standard platforms.. 

2.Side Platform

 Also referred to as a through platform, the side platform is a common type of railway platform situated alongside the railway tracks. Stations with side platforms typically have two platforms—one for each direction of travel. This configuration facilitates easier crowd management and passenger flow. However, the construction of such platforms requires more space as compared to the other platforms.

3.Split Platform

A split platform, also known as a separate platform, features distinct platforms for each track, allowing for a narrower horizontal layout of the station. This design divides the platforms into two or more levels or sections. This helps to manage trains efficiently. However, this involves complex construction. It could make it difficult for the passengers if marking is not properly done.

4.Island Platform

The island platforms have tracks on both sides. Passengers can access trains on both sides of the platforms. It is efficient as the space can be utilized properly. However, it can lead to crowding if the passenger’s management is not proper. 

5.Elevated Platform

These platforms are raised above ground level with the help of columns and structures. Such platforms are used in densely populated areas to separate tracks from the street-level traffic. The construction and maintenance of these platforms can be difficult. The mobility on these platforms could be a barrier for people with disabilities. 

6.Underground Platforms

These platforms are located below the ground level, using the space below the streets. The construction of these platforms is difficult and becomes more complex in areas with high water levels.

7.High-Level Platforms

These platforms match the level of the train doors, making it easy for people to step in or out. It makes it easy for passengers with disabilities to access trains easily. 

8.Low-Level Platforms

These platforms are positioned below the train doors, requiring steps or ramps to access the train. It is less expensive to construct. However, it can be difficult for people with disabilities to access the trains, restricting their travel. 

Platform Screen Doors (PSDs)

Platform Screen Doors (PSDs), referred to as Platform Edge Doors, provide a physical boundary between the train and the platform. These doors act as an important safety feature that has been retrofitted onto numerous metro systems. They are a new inclusion to numerous metro frameworks around the world.

Necessity of Platform Screen Doors (PSDs)

Platform screen doors are necessary to secure the lives of millions of individuals who opt for public transportation. Within cities, public transportation provides a cheap and effective way to explore the city or reach the desired destination. These transports can be heavily crowded, resulting in serious and fatal accidents. Platform screen doors provide the security and convenience that passengers anticipate.

Types of Platform Screen Doors:

1. Full-Height Platform Screen Doors: These doors extend from the platform floor to the ceiling, creating a continuous barrier between the platform and the tracks.
   • Benefits:
     • Safety: Full-height PSDs offer a barrier that reduces the risk of passengers accidentally falling onto the tracks. 
     • Thermal and Acoustic Insulation: By extending to the ceiling, these doors provide enhanced insulation against external noise and temperature fluctuations.

• Design: The mechanical components, including the drive and locking systems, are typically located in the upper section of the door frame.

2. Half-Height Platform Screen Doors: Also referred to as platform edge doors or automatic platform gates, these doors reach up to chest-height, rather than extending to the ceiling.

• Design: The drive and locking mechanisms for these doors are often integrated into the lower part of the door system. 

Challenges Faced by Platform Screen Doors (PSDs)

1.High Cost

Installation and maintenance of the Platform Screen Doors (PSDs) can be a financial barrier for the central and state governments. The costs involved the custom designs of the PSDs for the specific stations. There was also the requirement for sensors, panels, motors, and regular repairs. It would also require regular inspection and maintenance in case of any defaults.

2.Technical Challenges

PSDs need to have a precise alignment with train doors. Any misalignment or difference in the placing of doors would cause operational issues. It was a complex task to align the PSDs with the existing station and train infrastructure.

3.Passenger Behavior

Managing crowds during peak times can be challenging. There are high chance that people entering the train press themselves against the PSDs, leading to wear and tear of doors and people getting hurt. 

4.Space Issues

There are stations which are small due to space issues or are densely populated. Installing PSDs at such stations could be a challenging task for the authorities. PSDs had to be designed with modifications for such stations to ensure the passenger movement is not harmed and it does not obstruct the emergency access.

Advantages of Platform Screen Doors (PSDs)

1. Prevent Falls

The doors are applied to prevent people from fatal accidents due to accidentally falling on the tracks. It also restricts people from committing suicide and homicide, where one person pushes another on the track. There have been cases where due to the high speed of trains and wind, people lose balance and fall on the trains, leading to injuries or death. To improve the safety of the tracks, PSDs are applied on every platform to reduce the risk of accidents.

2. Improved Station Environment

By physically isolating the station from the tunnel, PSDs allow efficient operations of heating, ventilation, and air conditioning. The PSDs enhance the sound quality at the railway or metro platforms. The background noise created when the train enters or leaves the station is reduced with the help of PSDs. It enhances the passengers’ experience and the sound of any announcements.

3.Reduced Litter on Tracks

PSDs prevent littering the tracks, which look untidy and raise the risk of fire. The PSDs prevent people from throwing waste on the tracks. It helps to make the station’s environment tidy and also helps the cleaning staff to pick up the waste from the platform without any risk. 

Conclusion

The introduction of Hyderabad-Vijayawada RRTS and improvements in the railway infrastructure play a crucial role in enhancing the public transport system of India. The strategic development of the train depot areas ensures that the rail services are effectively maintained and operated. RRTS projects promise a reduction in road traffic, shorten travel time, and encourage a sustainable transportation system. Platform screen Doors (PSDs) are another way to ensure the cleanliness of the stations along with passenger safety. These developments offer a safer, more effective, and more ecological mode of transportation while overcoming the cost and technological constraints.
