That's another good answer and especially during R179 dealing with issues I haven't seen how new modifications works, on R160 similar never had a problem but R142 is also made from bombardier that some mechanical had a problem too and R179 are made in Canada and assembled to new york plattsburgh and About the board announcements on the ceiling in the train it looks similar R142 white announcements board and R179 black announcements board I could tell the difference between each other.
