Jack,
CP units went in for scheduled maintenance every 90 days. These inspections
are called Datal inspections on CP. By setting a regular date for inspection,
the home shop would know when the unit is coming in and have required parts
(oil filters etc.) on hand. Also, the units were scheduled to allow a steady
flow of units through the shop. Of course, sometimes units break down, so then
the unit comes in for an unscheduled visit for repairs. Datal inspections vary
from a (small) 3 month inspection to a (bigger) 6 month inspection to a (large)
annual inspection. Every 2 years (24 months), included with the inspection,
would be an air brake change out. Portions of the air brake system were
swapped for cleaned and tested parts to ensure reliable operation of the brake
system. The air brake change out is mandated by Transport Canada for safety
reasons.
Each unit was assigned to a home shop which is responsible for maintaining the
unit. When a unit was getting close to its due date, the unit would be worked
back to the home shop in time for it's inspection.
Today things are a little different, but that is how it was done back then.

Hi!
Two questions:
A.) What was (or was there a) rule of thumb as regards when diesel locomotives
were "shopped" for regular maintenance?
2.) How were vans assigned in the 70s?
Thanks!
Jack.
