Maintenance schedule

  • This might be an interesting concept of adding operational features to your modeling, of how a shop works. The time period being around the 50s to the 80s, and most of the following maintance schedule has changed since then, due to technology.


    Maintance of locomotives at Western Pacafic was desinginated by and determined by days, months and years. For example a turn is a daily inspection and sanded, fueled and lubricants topped off and kicked to the outboud ready track or garden (holding track ajacent to shop)


    Every seven days was called a "full Service" FS, unit moved into the shop, oil sample, lubed traction motors, ring inspection, and some filters changed out. rolling inspection of wheel tread

    This is a two hour to 4 hour or more depending on what was found needing repairs.


    Next was a MO or Monthley, in shop and heavier inspections and repairs, this takes from 4 hours to a day depending on the repairs needed.


    next is the "Quarterly" Q, heaveryer insp then a MO, but not as much as an as a SA


    next is the "Simi annual" SA (6 month) unit in shop and considered dead work as the inspections and repairs modifications and such were more in depth.


    And lastly the "Annual" A , This could take two to four days.


    So basicaly the abvove means that a unit is inspected as a turn for 6 days, the seventh day its a full service and repeats for 30 days becoming a MO monthly, and so on untill the unit is back shoped becoming an Annual.


    If you are into clock time and realistic operation on your layout you could desenate a few minits difference for various repairs, but if you do this will keep a hosler very busy building and takeing apart consists.


    Well lets get back to work, this shop has three leads coming into the round house, inbound where we sand, fuel and top off units, a center track (used for inbound or outbound) and an outbound track where units are coupled togather into consists, and then air brakes are checked as well as electrical. When all three inspectors (machinist, electrican, pipe fitter ) give the thumbs up, it is released to service, locomotive road crew jumps on and its on her way.


    Not much of a blog but I hope you enjoy it, perhaps the next time a blog about the inbound and outbound lead workers and how they cordninate with each other
