1. Signalling 

Did you know that the signalling system tells the trains when to stop or move? This system has now been upgraded to a new Communications-Based Train Control (CBTC) technology that allows our trains to run closer together. With the capability to run at a 100-second headway, compared to 120 seconds before 2018, commuters now enjoy a shorter wait before the next train comes!

2. Power supply

Running at a higher capacity is well and good, and we want to be in no doubt that our power supply is up to the job. The existing power supply system has been upgraded to ensure just that. Besides replacing the existing, aging equipment with a brand new one, the system now comes with real-time condition monitoring abilities! This means it’s able to check on the health of our power supply system and detect faults, such as damaged insulation of the traction cable! The system also comes with an intelligent Fault Isolation System (iFIS) for identifying the location of a cable fault. This allows for faster response, isolation and system recovery.

With these enhancements, we now enjoy an improved overall reliability of our railway system. Just watt we need.

3. Track circuit system

Working in tandem with the CBTC signalling system is a new track circuit system. Track circuits detect the presence of a train on the track, which helps us to speed up train recovery efforts in the event of a signalling system failure. The new track circuit system doesn’t just spot trains, either. Any broken rails needing repair can be identified, and its built-in condition monitoring system is able to pre-emptively address track circuit-related failures before they occur.

4. Sleepers

Railway sleepers not only hold down two rails of a train track at the correct spacing, but also distribute the load of the train over these tracks, ensuring a smooth ride for everyone.

While sleepers have traditionally been made of wood, we now use pre-stressed concrete, which are more weather-resistant. These robust sleepers are expected to have a lifespan of 50 years, providing long-term durability and reliability!

5. The third rail

The third rail runs alongside the running rails on the track and is responsible for supporting the supply of traction power to our trains. In the span of two years, we replaced 180km of this third rail to mitigate the effects of daily wear and tear on the old rails. This reduces the likelihood of power faults. With new power rails, we effectively minimise potential downtime, providing a more reliable and efficient rail system for commuters.

6. Trains

Say goodbye to the first, second and third generations of trains! In 2018 we bought 66 new ones, and another 40 in 2020, which will gradually replace those on the NSEWL. These will be the 7^th generation of rolling stock employed on the lines.

What’s new? Sensors that enable monitoring, diagnosis and pre-emptive action for improved performance. Commuters will also feel the difference with more open space, ergonomic seats, colourful LCD displays and more panoramic views out of the larger windows. These trains are more inclusive, too: they allow easier boarding, and are friendly for prams, wheelchairs and foldable bicycles too.
