As it is almost impossible to track the pre1900 locomotives with 
each division getting locomotives to meet their needs from 6 
company shops a number of builders. Then the rebuild programs at 
each shop added a complex mix. In 1905 with the setting up of the 
new classification system the Lehigh Valley had 51 classes of 
4-4-0 in the E class with a good number of  the smaller older 
4-4-0 gone. In 1905 locomotive were renumbered and all pre 1905 
numbers are not shown.
