Not a specific consist, but typical.

After the fall 1970 timetable change, the twin-unit diners disappeared in favor of an ex-NYC grill diner. The IMPERIAL sleepers also disappeared. The CREEK sleepers were a sometimes thing; but, usually not. The 10-6s could be about anything that PC owned, and the 6 DBR sleeper-lounge was either an ex-PRR FALLS series car or an ex-NYC STREAM series car. Also, 1 GG1 became the norm.
