Valuation Maps FAQ

A unique valuation section number was assigned to each right-of-way, property location or entity owned by a railroad. Section numbers were assigned within a state. A few section numbers never had maps drawn because there was no property associated with the section. A line that continued through multiple states would have mutliple valuation numbers. When a railroad was purchased or leased, a new valuation number might be assigned. Some maps might have had 3 or more numbers over the lines lifetime.

Valuation maps were generally drawn from East to West or South to North. Because many lines changed direction along their route, an individual map may have a different orientation. Map numbering would continue sequentially.

Valuation Maps were drawn on 24 x56" tracing cloth (linen) and blue prints made from them. Originally blue prints were whtite lines on blue and later were dark lines on a light background. In the east, maps were commonly drawn to a scale of 100' = 1" and covered aproximately 1 mile of right-of-way. Further west the maps were drawn to a scale of 200' or 400' or more = 1" and covered aproximately 2 miles, 4 miles or more.

Maps showed both track, structures and property owned by the railroad on the assigned date of valuation. The date was was generally assigned to the railroad by state for a year between 1915 to 1918 and the date of June 30. The map sometimes also showed adjoining property, structures and . If the area was complicated, a separate land and right-of-way map was drawn normally with a prefix of ST (T for Track) or SL (L for Land). Land maps normally included a schedule of property showing the grantor/grantee details including dates and where recorded. (Later revised maps may not include the schedule of property).If necessary, additiona sheets were made with just the schedule of property or schedule of side tracks.

The American Railway Engineering Association "Conventional Signs for Use on Topographical, Right-of-Way and Track Maps" shows most symbols used on the maps.

Station Maps

If a map got to complicated, it was divided into more detailed Station maps often with separate track and land versions.

Branch lines and spurs could be included in regular map numbering or or might given a separate sub number or an entirely new number
