Plan of Steel Work
The title block says: "P.R.R. Co., Western Lines, Type "A" Engine House, Crane Section-Steel Design, Plan of Steel Work, Office of Chief Engineer-Const, No. 18477". The drawing is dated June 17, 1918, revised Aug. 12,1918.
The top chord bracing is shown as dotted lines, and the bottom chord bracing is shown in full line.
At the bottom of the drawing is a schedule of engine houses that the PRR, at this time, was planning to build, indicating the number columns. The table reads:
- Stark Engine House, Cols 1-31 inclusive
- Crestline Engine House, Cols 1-31 inclusive, Temporary end on Col 1.
- Mosier Engine House, Cols 1-22 inclusive, Temporary end on Col 22
- Mingo Juct. Engine House, Cols 1-16 inclusive, Temporary end on Col 1
- Jeffersonville Engine House, Cols 1-16 inclusive, Temporary end on Col 16
- Scully Engine House Cols, 1-35 inclusive, Temporary end on Col 35
Of the six enginehouses on this list, only the first four were actually constructed. For some reason, neither Jeffersonville nor Scully were built.
The drawing also includes several notes.
