While rail could certainly help it would be over the long term. The pipeline company will have restored their operations long before the logistics of setting up loading / unloading points could be established, cars leased and positioned and rail service could begin.
Below is an article on setting up a facility in the Bakken. While it is from 2014, if you scroll down, you can see and example of a double track loading rack. Because the pipeline already has its gasoline, jet fuel and other products distribution infrastructure in place, there would be no incentive for a private company to invest millions of dollars creating rail facilities. To be sure, some Bakken crude was sent to the east coast but it was to refineries, not to distribution sites like an airport fuel farm.
