According to Ancestry:
"records will typically list an employee’s name, station, position, birth date or age, and various other details, such as salary, date entered service, and transfer information. For example, caution books list offenses employees were written up for and include name, date, grade, station, years of service, and date of suspension if applicable. Salary and wage registers list name, name of person recommending an employee for a position, date of appointment, salary or wage, dates of pay raises or decreases, age at the time the employee joined the railways, promotions, and remarks, which can mention transfers to different stations.
Records can be searched by name, birth year, event year, station, or company. Or they can be browsed by volume. In the browse, unless otherwise identified, the books are staff registers."
With nearly two million records in the database it's one worth searching in case, as sometimes Mr. Micawber's dream will come true, "something will turn up."
