Doubts about the consortium

When the defects from the relatively new C151A trains constructed by same consortium made public on 5 July 2016, the discussion of this incident has turned into a political issue in Singapore after Gerald Giam from the Workers Party had made a Facebook post^[4] about why the same consortium are awarded the subsequent contracts (Specifically both C151C and CT251 trains were awarded to the same consortium again in 2015, while the C151B was also awarded to the same consortium in 2012 instead) after the Land Transport Authority and SMRT officially knew the C151A crack defects as early as 2013.^[5][6]

The C151A trains that have surfaced issues, along with newer C151B and C151C trains are to be deployed in the East West Line and North South Line while the CT251 trains are to be deployed in Thomson-East Coast Line.
