Why is it the railroads DO NOT call out their FCC call sings on the radio? In the ham world, it is every 10 mins. Others, it is every 30-60? I thought identifying as: UP Spring Glidden Sub, is not enought for FCC rules.
The call can be in manual or authomated voice or Morse Code.

Probably for the same reasons police, fire departments and airlines don't use call signs.

From 47CFR, subpart 90.425 section 4:
(iii) In the Industrial/Business Pool, railroad licensees may identify stations by the name of the railroad and the train number, caboose number, engine number, or the name of the fixed wayside station. If none of these forms is practicable, any similar name or number may be designated by the railroad concerned for use by its employees in the identification of fixed points or mobile units, provided that a list of such identifiers is maintained by the railroad. An abbreviated name or the initials of the railroad may be used where such are in general usage. In those areas where it is shown that no difficulty would be encountered in identifying the transmission of a particular station (as, for example, where stations of one licensee are located in a yard isolated from other radio installations), approval may be given to a request from the licensee for permission to omit the station identification.
By the way, land mobile stations may now also identify digitally, provided that the FCC is given the details of the digital code used.
