Maintenance of Way Roster

The Pennsylvania Railroad is only known to have published a complete roster of maintenance-of-way equipment in 1941. Therefore, this roster will likely never be complete. Consider it a "best effort" project.

Please see the Field Definitions and Sources & Methodology below the search criteria section.

To maintain consistency in data entry and ease in searching, all class designations are entered in ALL CAPS and without hyphens.

Field Definitions

Marks - Reporting marks; not all items wore PRR reporting marks.

Road Number - MoW road number.

On Roster - Date introduced to MoW roster. May be build date, or date of transfer to MoW service.

Code - The 1941 roster had a car type "code" assigned to each piece of equipment. For instance, "301" was a "Side Dump, Clark"; a "401" was a "Wreck [service] - Tool".

Use - The 1941 roster had a car "use" assigned to each piece of equipment. For instance, a "Side Dump, Clark"; a "Wreck [service] - Tool".

Class - The class of equipment in MoW service.

Code2 - Similar to "Code", there are codes relating to some later data indicating the type of car. Examples include "SUP" for "Supply", or "RSPS" for "Russell Snow Plow Single". It is possible that these were Penn Central or Conrail designations.

Photos - References to photos in print.

Notes - Any additional available information.

Assignments - Known assignments.

Prev Number - Road number prior to MoW service.

Prev Class - Class prior to MoW service.

Prev Name - Car name prior to MoW service. Typically applies to former passenger equipment.

Sources & Methodology

Data was culled from the following sources:

  • Pennsylvania Railroad 1941 Roster of Maintenance of Way Equipment - Transcribed by Bob Johnson and Ian Fischer and provided by Al Buchan. (Access to original document not provided.)
  • Keystone Crossings - Passenger Equipment Roster - Extracted records of passenger cars transferred to MoW service in the late 1950s through the 1960s.
  • William K. Volkmer - Bill oversaw the conversion of dozens of heavyweight passenger cars into MoW cars during the 1960s. He provided significant information on these conversions.
  • Ken McCorry - Ken had compiled a list of equipment via PRR survivors to the Conrail Roster and from photos. Where photos matched the existing roster (above), the photo reference was simply added. Where a road number was in conflict with the 1941 description, an additional record was added, with the thought being that the 1941 road number was retired and the road number was re-used.
