Multi-field searches are evaluated on an AND basis.
Only fields with criteria entered are evaluated during the search.
The "@" symbol may be used for wildcard searches, including used alone to retrieve all records.
To maintain consistency in data entry and ease in searching, all class designations are entered in ALL CAPS and without hyphens ("-"). It should also be noted that for many years the PRR used an "R" suffix to designate cars with air conditioning. This practice was dropped in 1954 and this database does not include the suffix in the class field.
