Here is an excerpt from an employment listing on the Alaska Railroad web site: "Approximately 12 positions to fill as a Locomotive Engineer/Conductor Trainee - The majority of new train service employees typically work on an "extra board" for the first several years of employment, dependant on seniority. (Regular assigned jobs are available but are usually occupied by senior employees). Extra Board positions have no structured days off or predictability as to when a call to work will be received. Employees in these positions must be available for a call to work 24 hours a day, seven days a week, unless in a mandatory rest period following a working assignment."
As far as I know, the ARR is experiencing an expansion of both freight and passenger traffic. This was helped along when they started running passenger trains from Seward, where they are able to meet the cruise ships.
I would think there is a few retirements taking place too. I know we have a bunch here on the UP. Greg
