Rail road Bridge at Second Narrows

[shorebird]

Any Vancouver locals give me a heads up on having the railroad bridge raised at second narrows? Are they 24/7? What frequency do they use? Is there a phone number instead? How soon before arriving should one call? Can you pre-book to plan around train arrivals? What is the clearance with the bridge down at low water? All that and any other tips appreciated.

From Wikipedia

A bridgetender activates cables and counterweights to raise the span. Unless moving a train across the Burrard inlet, the lift section is always in the up position to allow ships to go underneath.

When in the down position the clearance of the Second Narrows Railway bridge is only 10.7m (35 Ft.). If you need the railway bridge lifted, you will have to contact the bridge operator on VHF channel 12.

Yes they are 24/7 and there are about 20 trains a day crossing so timing is tight.
