Melbourne's train network faces near total meltdown on Wednesday with the drivers' union planning industrial action that will take more than half of Metro's train fleet out of operation due to safety fears.
The planned action will affect trains from first service on Wednesday and continue indefinitely, crippling the city's metropolitan rail network, which carries 232 million passengers a year.
Metro has put an application before the Fair Work Commission calling the union's planned action for Wednesday unprotected.
For the Siemens trains they've had a few units with the capacitor in the static inverter under the T car going boom. Sending the cover flying into the next postcode.
With the comeng fleet the new DTRS has been giving them problems. It's all now linked up with the DDU and they've been having problems with the PA communicating when the power goes out. The old analogue system there was a battery backup and the radio and DDU(which controls the PIDs and CCTV equipment) were seperate.
