Yellow Line Safety Issues

Now that it seems to be legal for someone to push someone else past the yellow lines and there are no longer ttc safety officers to assist, I would like to know what the TTC will be doing to protect the commuters that use the system every day.

There has been talk of security barriers being to costly but what about two young lives. If you feel the same let the new mayor of Toronto know your concerns. He is all about Transit changes. This would be a huge one.
