Railcar Gauge Tables

Gauge tables show the tank car capacities or volumes for various liquid levels.  Other common names include:  strapping charts, capacity tables, outage tables and innage tables. In order to check your rail status, you will need the car initial and car number, often referred to as a CARINO. These initials and numbers are given to a railcar by the AAR as a means of car identification.

• The car initial or Car Mark is a two-to-four-letter alphabetic code, frequently referred to as Reporting Marks.
• The car number is a one-to-six-digit number.
