Hi,
From the WP&Y site for all passenger cars,
"The total length of all cars is 3,243.1 feet with an average length of 45.4 feet."
Out of curiosity, if you lined up all the C&TS equipment, how far would it streach?
Put on qualifiers if you want (ie tank cars only or passenger cars only including converted box cars or drop bottom gons only etc.)
