Looks like the webmaster of what used to be the "Train Symbol Guide to the Pony Express" has updated his page and is in the process of updating it some more in the coming days and weeks under a new name called "THE Train Symbols Website". Check it out and be sure to give him the correct train symbols, right now he has NS, CSX and UP symbols. He is working on BNSF and will probably have more later.

Great! Thanks for the notice.
I've kept a copy of that Excel Spreadsheet on my desktop for years . . . . . glad to see an up-dated file.
Happy railfanning,
