1930s Electrical Engineer's Drawings for N.Y. Central Railroad

1930s Electrical Engineer's Drawings for N.Y. Central Railroad

135.00

This is a collection of 1930s engineers’ drawings for railroads. From the handwritten notes attached to (or loose in) this collection, it appears that they were initially gathered by the Electrical Engineering Department of the New York Central Railroad, namely by K.B. Rowell, one of the department engineers.

One sheet, for instance, is labeled “Curved Track Studies.” Another, “DEs3 Chicago. Computations in connection with layout of study on Maximum Radius of Track Curve with Third Rail.”

There are 11 drawings (a number of them are actual blueprints in a variety of sizes) from NY Central; 7 from General Electric Erie Works; 1 from Lehigh Valley Railroad; 3 relating to Grand Central Terminal improvements. This totals 22. Additionally, there are 18 pages of computations. All told, there are 40 pieces.

Also, group of the engineer's R2 & DEf computations for laying out on curves of 230’ and 301’ radius to 13-31 6/23/32

Condition: Overall condition is very good excellent. Of the 40 pieces there are 5 that have very slight moisture stains, the rest of them show no signs of moisture. None are torn and the paper structure has not deteriorated.
