I checked and found out that C851 is actually the contract
awarded to constructor for building CCL tunnels and MRT station. So
I want to rectify the error I made when I remembered the Contract
Number wrongly that it is used for awarding contract to train
manufacturer.
C851A is the contract being awarded to a constructor to
construct Bartley CCL station. But I cannot find C851 without "A".
So it is safe to assume that C851 is for constructing the CCL
tunnels along Bartley Road.
So the 4th series should be labelled as
C951. LTA put up the tender on C951 Electric Trains in Nov 07
and has since extended the closing date to June 08. We will know
the result of which train manufacturer will be awarded Contract 951
in early July 08.
I think C951A/C951B train will be designed, developed, tested
and deployed for possibly Downtown Line and NSL/EWL extension
respectively. Or maybe C951 is solely for Downtown MRT while next
contract on train could be the one for NSL/ELW extension.
Downtown and NSL/EWL will HAVE to use different
trains if Alstom wants to bring in Metropolis for DTL.
Because the track systems are different, an Alstom cannot run on
EWL or NSL. Even though for the CCL they are also using 750V DC
power, but their track signals are totally different. So we can
readily assume that Alstom cannot run their Metropolis on the EWL
for the Joo Koon extension. Or unless if SMRT wants the DTL to use
the same type of trains and their train signals for EWL/NSL,
then it is possible they order as a bulk.
