Keystone Crossings offers several searchable databases (under the Data tab). One of them is Passenger Consist Reports. This database provides searchable access to CT220 reports, which is the passenger equivalent of a conductor's wheel report on a freight train.
Unlike the "Makeup of Trains" books which dictate how many and of what type of cars are to be assigned to a given train, CT220 reports indicate exactly which cars were used on a given train on a given day.
Since inception about 18 months ago, the database has contained 501 records. Several hundred more were added today, bringing the total to 964, spanning the years 1942-1971.
These reports provide a trove of information to varnish modelers and historians alike. Enjoy!
