Norfolk Southern Train Symbols pre-1988

Hello, I’m looking for a list of NS train symbols prior to 1988 when they still used letters with numbers. I’ve looked all over the internet and can only find data after '88. My grandfather worked for the Wabash/N&W/NS out of Moberly, MO and I can remember him being called for TC-3, TC-4, etc. Any help would be appreciated. Thanks.
