Serious, technical question.
Why don't they make the MRT train longer.?
Instead of 6 units, make it 10 to increase the peak passenger capacity by 70% per train.
Of course, one technical issue would be that the platforms have to be made longer to accommodate the longer trains. But if the 2 font and 2 lead carriages are internally resigned for seating, then people from the rear and front can move easily to the main 6 segment of the train for boarding and de boarding.
Then the train can still stop within its present designated position
of six carriages, without the need to do any mod to the existing platforms.
The other major technical issue would be the increased loading current,, for which the present electrical conductors may not be able to handle. A simple solution would be to have an ON DEMAND onboard small generator ( 2 MW ?), to provide the additional booster power during start up from the station or elsewhere.
Alternatively, increase the present 750 Volt supply to 1000 volts, with appropriate step down mod on each carriage motor. Which is not that difficult or expensive.
These trains can be used during peak hours, and for non peak hours, the normal 6 unit trains can be run.
Any techie here to discuss ?
