1 thing they are dragging the time is because the bus itself was
in Australia specification without rear window. If I'm not wrong,
it could be a LTA rule as well that public buses need to have rear
window... SMB138Y was sent back to STK, might be this fact...
138Y was not sent back because of the lack of rear window, it
was because SMRT did not want the bus as it was using Ventura doors
since the rear doors were slow in closing, according to the STK
staff which I talked to during the SMRT carnival. STK had already
attempted selling the bus 2 times at a reduced price and 2nd time
as a training bus, but SMRT rejected both offers. Currently there
are no buyers for it, but since SMRT Enviros are using Ventura
doors, STK may attempt to sell it to SMRT once more according to
him.
