Southern Haul Cargo Railway owns all of the railroad tracks in the city of Woe-be-gone, Idaho. Because of Woe-be-gone's sudden population explosion, Southern Haul Cargo is planning to make a Metropolitan Rail and Subway system using its pre-existing tracks. The city council has concluded, however, that if the cargo railway were to offer subway transport, the transport system would have an unfair advantage over the city's existing bus routes, because Southern Haul Cargo's subway system could be subsidized by the profits of their monopoly on cargo transport.

Based on the information given above, which of the following questions can be answered?

【选项】Is the cargo railway forbidden to offer bus transport?
