Which code is used for the Train Order Home Control Relay?

Explanation:
Relays in this signaling system are identified by short mnemonics that map to their function. The Train Order Home Control Relay is labeled with the code that directly reflects its purpose: Toh. This makes it the best choice because it uniquely identifies the Train Order Home function in diagrams, wiring lists, and maintenance references. The other codes correspond to different relays or general functions and do not represent the Train Order Home function. If you look at the system’s code legend or schematic, you’ll see Toh specifically reserved for Train Order Home, which is why it’s the correct designation.
