SINGAPORE - Two new train cars were added to the Bukit Panjang LRT system and started service on Wednesday morning.

Another 11 new train cars will be progressively put into service and will be in operation by the end of next year.

The new cars, which join the existing fleet of 19, will help to ease congestion during peak hours and improve frequencies said the Land Transport Authority.

Manufactured in the United States by Bombardier, the new cars can carry up to 105 passengers and feature more handrails and improved air conditioning.

The Bukit Panjang LRT system, which is run by public transport operator SMRT, has had a number of disruptions over the years. This includes one major incident in April 2012 where 11 passengers had to walk along the LRT tracks to safety after the train they were in stalled.
