Reminders are devices used by the signaller to prevent a control from being used. Also known as "collars" after the metal rings used for this purpose in mechanical signal boxes, placed over the lever to prevent the latch handle from being pulled and thus locking the lever in place. In IECCs and in SimSig, they're built into the control software. When you cannot place a route over a section of line due to the presence of reminders, the line is said to be 'protected'<ref>I think. Can someone confirm?</ref>. | |||

Back before track circuits, they were an essential way for signallers to not overlook the presence of a train. The Quintinshill disaster of 1915 was caused in part by the signaller's failure to place collars on the signal and/or point levers which would've prevented setting a route into the line which held a waiting passenger train - and the train crew's failure to ensure the signaller had applied such a protection. | Back before track circuits, they were an essential way for signallers to not overlook the presence of a train.

In SimSig, ordinary reminders appear as a cyan background behind the control. As well as signals, you can also collar Auto and Emergency buttons, points (after they've been locked into a position), entry and exit buttons, lever frame releases, slots, level crossing controls… The simulation host can also set reminders on track circuits (via the F11 menu), which prevents routes being set over them. | In SimSig, ordinary reminders appear as a cyan background behind the control.

To set a reminder on something, click on "Reminder" next to the clock and then click on the thing you want to collar. To remove a reminder, click on "Reminder" then right-click on the collared thing. | To set a reminder on something, click on "Reminder" next to the clock and then click on the thing you want to collar.

If you click "Override", you can "click through" a single general reminder without removing then reapplying it. | If you click "Override", you can "click through" a single general reminder without removing then reapplying it. | ||

Reminders also stop ARS from setting routes, but they do not affect automatic signals. If you need to collar an automatic signal, you can pull the E or R button and collar that instead. | Reminders also stop ARS from setting routes, but they do not affect automatic signals.

As a very general rule, to protect a specific section of track, it's better to collar the exit signal than the entry signal, as this lets you set routes closer to the protected track (but not too close). | As a very general rule, to protect a specific section of track, it's better to collar the exit signal than the entry signal, as this lets you set routes closer to the protected track (but not too close). | ||

It's good practice to apply reminders liberally, particularly in multiplayer sessions. Unlike sticky notes, reminders are visible to other players. | It's good practice to apply reminders liberally, particularly in multiplayer sessions. Unlike sticky notes, reminders are visible to other players. |
