Vancouver Mayor Gregor Robertson said he would’ve loved to have ridden a train south to bolster Cascadian economic ties in Seattle and Portland — but there was no train to take.

“We have one train a day that leaves Vancouver in the evening,” said Robertson yesterday. “It’s not convenient.”

The mayor said a second Amtrack train would generate tens of millions in economic “uptick,” but is being held back by the feds who want to charge Amtrack $1,500 a day in customs and immigration costs.

The second train, as well as a potential high-speed rail link connecting Vancouver-Seattle-Portland, will be on his agenda when he meets his counterparts in the two cities this week.
