Don't know how common carrier obligations work specifically for railroads, but in my industry, telecoms, the general principle is that any given service is priced the same way for everybody, and any one who wants a given service can get it, so long as there's sufficient capacity. It doesn't obligate a telco to offer any particular service in any particular location, although other regulatory obligations, such as with (publicly subsidised) universal service programs, might.
Not all services offered by a telco are common carrier services. Some, such as plain old telephone service - POTS - are, some aren't. Assuming the FCC's December decision takes effect as planned (still a couple of procedural hurdles to go), broadband will no longer be a common carrier service.
The nearest analogy to rail that I can think of is long haul fiber. Company X might have fiber that runs from point A to B to C, but even if it offers service between A and C, it doesn't have to offer anything in B. Anyone can buy service between A and C at the tariffed rates so long as there's capacity, but there are a hundred exceptions (e.g. sales and promotions) to the tariffs.
