Grade separating level crossings has numerous benefits: it allows more trains to run without impacting on others, it cuts delays to motorists, bus/tram passengers, pedestrians (including train users) and cyclists.
And emergency services.
Clayton is particularly bad for this, because it’s so close to Monash Medical Centre, but it’s not uncommon to see ambulances or other vehicles waiting at suburban boom gates… here’s today’s in Bentleigh, a short time ago:
In this case the total delay was perhaps about 2 minutes, while a freight train passed. Hopefully it didn’t make a bad difference at the emergency.
Thankfully Bentleigh is of course one of numerous crossings being grade separated in the next few years. I’m told locals can expect a project update in their mailboxes (real and email) in the next week or two.
