Caption: CN Z149 had a nice leader on two consecutive Saturdays in late March/early April 2022, here we can see the latter rolling under Warden Avenue in Markham, ON with the Wisconsin Central heritage unit on point. 149 the Saturday before was led by BCOL 4642, at the time the only active locomotive on CN in the BC Rail 3 colour livery, which had nearly every railfan along the Kingston/York subs trackside.
