Unpopular Opinion, but I think Melbourne should of extended the Cragieburn Line to Wallan, and electrified out to Melton and Wyndham Vale as well as also build the Airport Rail Link before even considering the suburban rail loop. And even then, the SRL should have been something like Brisbane Metro BRT, not a rapid transit line. It doesn’t even go into the city which is where majority of people using the trains actually work. So therefore the only few people using it will be schoolkids, and a few crackheads. Meanwhile the Western and Northern parts of Melbourne are growing and are dying for better transport. SRL East only benefits those in the wealthier eastern suburbs.
