LTA had commercialise the train network in Singapore. It is run by SMRT and SBS Transit. With the advancement of technology, an app for smart phone is still not visualize yet. They have leave this job to our government agency, LTA.
LTA had developed its own app but this does not address the needs of the commuters of Singapore at large. The announcement normally come later than Twitter as information need to shift through multiple channels.
Just look at the comprehensive app own by HongKong MTR. It highlight the breakdown to commuters by using their app with more information than LTA.
Singapore is at least 3 years behind HongKong in the development of smart phone app for the train network. I will see whether Mr Khaw, the new Transport Minister can realize this dream for Singapore.
