Are you saying the NKP never ran sections with their freight ? So you're saying you would not find green class lights / flags on their freight Berks? That may be the case and I have no idea where to find a timetable from that era. However Sections were a great way to get trains over the road with limited train orders and less running orders.
When I started in 65 with Canadian National we used the same rule book as the Chesapeake & Ohio, New York Central and the Toronto Hamilton and Buffalo plus a number of other Canadian railways so we're not that different.
