00:00 So Ben, what do we have here in the signal box?
00:07 Alright, so welcome to Hamilton in the signal box.
00:11 Over here, for decades, signalers used to stand here and watch Beaumont Street to make
00:16 sure that the crossing was safe.
00:18 And here they operated the crossing controls with the lights on.
00:22 And obviously that's happening in the simulation.
00:28 So they controlled the crossing there.
00:31 Through here we've got the main lever frame, which is the main signaling control for the
00:37 signal box.
00:38 And with this, points and signals were basically cleared by the movements of the signaler.
00:46 Down further, or up here sorry, first we've got a diagram showing where the signals are
00:54 and how you operate in the signal box on that move hop, what's called the pulling list.
01:01 And further down, we've got the track circuit indication diagram, which tells us where the
01:10 trains are.
01:11 Red levers are for signals.
01:13 White levers are spare levers, so they were levers that used to do something and no longer.
01:17 Black signals are for points.
01:19 And blue levers are for locks or releases.
01:23 Up above the lever frame we've got the block shelf, where we have block bells, which is
01:29 what the signal boxes used to use to talk to each other.
01:32 We've got some indications telling us what's happening at the next signal box.
01:38 And down below there we've got signal repeaters, and they were called frog repeaters because
01:46 they were five little frogs.
01:51 Here we've got the desk where the signaler worked.
01:55 And then the last sort of point of interest is the train register table, where the signalers
02:05 record all the details of the train movements in the train register book.
02:10 And here's the little secret device which makes all these old levers work, that model.
02:15 In here, and for one sneaky peek only, is Ben's secret magic box, the program logic
02:23 controller.
02:24 And that takes the signal movement into the computer and then makes the little model work.
02:40 We just take the leg of Hammington Camanoff and in there, the fire is on, the signaler
02:46 is working.
