In an effort to avoid duplicate failures, the operators of the Yellow and Red lines are now testing redesigned manual wheel and conductor rail systems.
Following new incidents where a guide vehicle fell from a running Bright Line train and caused similar harm to a lengthy section of the Pink Line’s conductor rail, the roll-out follows these incidents.
Following these incidents, Alstom, a French manufacturer of monorail guide wheels and conductor rail systems, and Eastern Bangkok Monorail Co ( EBM ) and Northern Bangkok Monorail Co ( NBM ), concessionaires of the Yellow and Pink Lines, have been working together.
They want to avoid any relapse of these shortcomings, Surapong Laoha-Unya, senior director of BTS Group Holdings Plc, told the media on Saturday. He was speaking as both EBM’s and NBM’s producer.
According to Alstom, Alstom has conducted internal screening of the updated manual wheel system, which has been put on two Yellow Series trains and one Pink Line train for further testing. The project will take about three months to complete, he said.
Early next time, he said, EBM and NBM may start replacing all of the manual wheels on their 42 Pink Line and 30 Golden Series trains.
Now, the Yellow Line trains are using an intact link vehicle style after a health examination, he said, adding the consistency of inspections has been raised following the accidents.
Alstom has even redesigned the wire bridge technique for both rail lines, according to him, but it is still looking into the benefits and drawbacks of the new design.
EBM and NBM have both requested that each part of the wire road, which is now about 5 to 6 kilometers huge, be divided into shorter areas to reduce the damage in the event that any section becomes problematic in the future, he said.
