Monday’s commute was a lot different for many of those travelling through Union Station.

The second platform, which separates riders on the University and Yonge lines, opened at 6 a.m.

It will service riders going north on the Yonge line, so those taking the University portion of the loop will continue to use the existing platform.

TTC spokesman Brad Ross said 30 customer services representatives will be on-hand during the morning and evening rush hours to help commuters get the hang of things.

“There’s going to be a little bit of confusion, there’s no doubt about that,” Ross said on Sunday.

“That’s why we have as many staff as we possibly can and all the signage that we will have to help people limit that confusion.”

The platform is much larger than the current one, which is narrowest on the entire system.

The University line was closed from Union to St. Andrew stations over the weekend as crews worked on the second platform.

“We’ve been working night and day for the last three to four weeks,” project manager Malcolm MacKay said on Sunday.

“It’s going to be airier, brighter, less crowding. Right now we have doubled the capacity.”

Renovations on the University side of the platform will begin in small portions at a time starting on Monday.

The TTC claims that their portion of the construction at Union Station is running on schedule to be completed by the spring of 2015.
