? about CN F-Units

Did CN ever run without B units when using A units regarding there F-7s?

In answer to your Question, yes they did.
ex-CN F9B


That is not a B Unit that is a HEP (Head End Power) Hotel Power Generator car that provides heat and electricity for the passenger.

Some of these HEP Units are modified F B Units. Ontario Northland Railway and GO Transit are some prime examples modifing either F7 or F9 B Units (not sure which) by removing the locomotive primemover and replacing it with an HEP Generator.

Actually the second car in that pic is called a Steam Generator Unit.
When CN dieselized, they needed steam heat for the passenger cars and these cars were built with boilers in them to create steam heat.
