There is no rough patch of track.
TTC's operators. The first set of classes completed their training on the Eglinton Line, the second set had their classes interrupted about two-thirds of the way through. The third set of operators - the ones that were going to be the first ones trained on both Eglinton and Finch West - have had their training dates postponed indefinitely.
Only in general terms.
The gist of it is two fold: that there was a major signal system failure on the Crosstown early November, and they have been trying to resolve it since then. This is what halted the second set of classes for training the operators. On Finch West, the TTC has still not been given full access to the line, as Metrolinx and Mosaic are still hashing things out.
If you'd been following, you'd know that no, it doesn't take a year to train an operator to drive a streetcar.
As well, these aren't streetcars, and it still doesn't take a year. The TTC requires 30 days of training, the same as a subway operator as - despite what a lot on here want to believe - the line is as complicated to operate as a subway.
