Thanks. I couldn't find it, but I knew it was there somewhere. So, it was a Safety rule, not GCOR:

Regarding switch point locks: I have worked on several railroads where the handles were painted yellow. A good reminder, especially if you don't use the switch much. There is a moment of confusion why the switch won't throw until you remember the second lock.

I did find ir in the 2005 BNSF TY&E Safety Rules:

S-13.7.4 Operating Switch Point Locks
When working with switches equipped with switch point locks (so designated by yellow handles):
1. Know the difference between the two basic types of switch point locks.
2. Remove the padlock from the switch point lock.
3. Use your foot only to depress the pedal, which places both types of lock under spring tension.
4. Snap the switch point lock into locking position by returning the switch to the normal position. Inspect to assure the locking position before putting your hands near the switch point lock to replace the padlock. If the switch point lock fails to snap into locking position, reopen the switch and repeat the process.
5. Do not attempt to pull up the pedal by hand or other means. Contact the train dispatcher and report the switch point lock defective. Tag out the switch.
Repair or correct defective switch point locks only if you are a qualified Maintenance of Way employee.



The latest version of the Safety Rules (when I re-checked this info) completely omits rules 13.2 through 13.7, which is why I couldn't find it after I checked all over the place. I was pretty sure it was in GCOR chapter 8 - Switches, but couldn't find it there. I had a coworker recently feel sharp pain between her shoulder blades when she unlocked a switch and tried to throw it, only to be jerked to a halt by the switchpoint lock out of sight on the other outboard rail. She stated it unlocked and started to open OK which is why she didn't feel anything was wrong with it, but we both remembered this rule. BNSF started painting every switch handle orange on our district a few years ago, so now I guess we'll play hide and seek with every switch.
Thanks again for your help.
