ICC Valuation Maps
Valuation maps are organized by Valuation Sections. Within each section there are various valuation sheets. There are multiple types of valuation maps; Right of Way, Index, Track Map, Land, Station and combinations of those. There can be others that are more specialized.
In general, valuation sections from 1 to 49 were associated with Boston and Albany, 50 to 199 were associated with the NYC Lines East and 200 and above were associated with Lines West. Over time, these did change as railroads were acquired and fully integrated into the New York Central.
The short hand used when talking about this is that the valuation section becomes just V<number>, so valuation section 125 is V125. The individual sheets are just numbered, so that sheet 5 of valuation section 126 is V126.5.
An example of the changes over time is the Zanesville Terminal Railroad (ZTRR), which was operated by the Zanesville and Western Railway Company (Z&W Ry), started as a valuation section 1 sheet 1 of the ZTRR, because the Z&W RY valuation section 6 sheet 1 (or V6.1) and the Z&W Ry valuation section 6 and index sheet, because it contained both the index of the maps and was the first sheet of the section. The transition from ZTRR to Z&W Ry occurred on June 30, 1918 and after December 31, 1921 it was operated by the New York Central Railroad.
