Attached is a pericope from from the Form 699 document, which deals with the clearance standards used by the railroad. Not included in the attachment are the actual state regulations, which comprise the rest of the Form 699 Document. The part which deals gases/liquids and compressed gases places some interesting restrictions with regard to clearances. Use of these restrictions in a model railroad setting might add some interest to operations. View attachment frisco_clearance_form699.pdf
