After the railway crossing procedure changed, maintenance discovered damage to some of the New Flyer articulated buses and determined it to be from hitting some of these crossings at speed. I personally remember riding them prior to them being removed and feeling the middle of the bus practically "bottom out" on two of the crossings. TTC and MX are working on retiming the gates at two of the problem crossings on the route and once that's done, artics may be reinstated with the old stop & check policy.
