In a Facebook post by the Land Transport Authority (LTA) on 2 April 2021, two sets of retrofitted Bukit Panjang Light Rail Vehicles (LRVs) have arrived in Singapore from New Jersey, USA! These two LRT vehicles are currently being secured at a work site beside Junction 10 Shopping Mall, awaiting to be hoisted to the tracks for testing and commissioning at Ten Mile Junction Depot.

LTA awarded Bombardier Transportation the contract to renew the Bukit Panjang LRT (BPLRT) on 7 March 2018.

This contract includes a re-signalling upgrade to the Communications Based Train Control (CBTC) signalling system, and also to retrofit 13 of the existing Bombardier INNOVIA C801A train cars with the new on board signalling equipment.

Re-Signalling to New CBTC System

Commissioned in 1999, the current signalling system of the BPLRT utilises the Fixed Block Bombardier CITYFLO 550 ATC system. However, having a Fixed Block system is a limiting factor for controllers to deploy more trains into the system to reduce waiting times for commuters.

When renewal works are completed by 2022, the BPLRT would utilise the Moving Block Bombardier CITYFLO 650 CBTC system. Commuters can then expect shorter waiting times with more trains deployed into the network.

Additionally, the Moving Block system has the ability to calculate a dynamic speed curve between trains, giving the opportunity for trains to brake more smoothly and more consistently – improving the comfort for passengers on board.
