    What is the distance from the top of the rails to the bottom of the catenary wire?

    Depends on which railroad you are modeling.

    See: http://www.trains.com/mrr/default.aspx?c=a&id=284
    "The New Haven's wire was strung from 16' to 22' high, lower than the national average. On the other hand, some of the PRR's wire was 22' or higher, depending upon its location."

    Google: (railroad catenary systems) for more information.

    Depends of what system your are modeling. Some railroads used PRR catenary standards EX: Virginian and Reading. PRR catenary trolley wire varies from 19'-0" min to 24'-6" max. The average height is 22'-0"

    Hi Zak,
    I have one more question about catenary systems. What is the center to center distance for the support columns for the catenary wires. You had answered my question about the PRR wire height of 22' sometime back.
    Thanks again,
    Ernie

    If you are talking from catenary structure to structure. The average span max is 270' This is from PRR catenary Standard Plans Electric Power System ET-1 June 10 1935
