It refers to &#039;Seaboard&#039; signals which were only identified by rule number in the old book and are now known as &#039;Standard&#039; signals in the 2014 rule book.<br /><br />There are some minor differences between the old Seaboard and new Standard illustrations in the rule book. For example:<br /><br />1) There are no longer dashes between the rule numbers and the rule letters. Rule 1281-B is now 1281B.<br /><br />2) There are slight differences in the indication punctuation. The old Rule 1281-C (and others) had a colon after the word &#039;switches&#039;, the new 1281C does not.<br /><br />3) The old Rule 1285 refers to &#039;engine&#039;, the new Rule 1285 refers to &#039;locomotive&#039;.<br /><br />4) The old Rule 1298 starts with &#039;Poceed&#039;, the new Rule 1298 starts with &#039;Proceed&#039;.
