# §236.301. Where signals shall be provided.


Signals shall be provided to govern train movements into and through interlocking limits, except that a signal shall not be required to govern movements over a hand-operated switch into interlocking limits if the switch is provided with an electric lock and a derail at the clearance point, either pipe-connected to the switch or independently locked, electrically. Electric locks installed under this rule must conform to the time and approach locking requirements of [Rule 314](/cfr/49/314.md) (without reference to the 20-mile exceptions), and those of either [Rule 760](/cfr/49/760.md) or [Rule 768](/cfr/49/768.md), as may be appropriate.
