I have been playing the Penzance sim and have encountered a problem with routing trains into the station and down sidings from the main line. I can send trains out of Penzance and route into the station from the depot. When a train approaches from St Erth I can set it from PZ2 to PZ3. I am aware that PZ26 has to be set first so I set this first, but it will not clear a route from PZ3 to PZ26. Is it something that I am doing wrong or has anyone else had tis issue?

You don't set a route from PZ3 to PZ26, you set the route from PZ3 to the buffer stop exit arrow in the appropriate platform.

Signal PZ26 is a preset shunt which can be used to reverse outside the platforms. You can ignore it for inbound trains and route straight from PZ3 to a platform.

SimSig, as it says on the homepage, lets you operate "signalling screens based on the widely used IECC and Westcad graphics used in the UK." It represents Penzance as though it were operated from an IECC-style interface and rightly requires you to route to the exit arrow, ignoring any running shunts (which are cleared for you), as you would in an IECC. Interestingly, the real Penzance has a lever frame, and despite having MAS, I believe if you were working the real frame, you would be required to pull 26 lever yourself before you can get 3 (or 4, or 16 as may be required).

Correct, and PZ3 is actually controlled from five levers in reality too.

With five levers you mean that there are five on whose state it depends?

Albert in post 133787 said:With five levers you mean that there are five on whose state it depends?No, there are 5 levers that can all cause PZ3 to show a proceed aspect if any of them are reversed, they are:- 3 - to Platform 3, requires 26 4 - to Platform 4, requires 47 and 26 12 - to Platform 2, requires 37, 32 and 28 14 - to Platform 1, requires 32 and 28 16 - to Sidings, requires 48 and 26 3/4/12/14 will all cause PZ3 to show either a Y aspect or a S aspect depending on the state of the platform the train is routed towards. 16 will only cause PZ3 to show an S aspect.

This is interesting information. Looks like it's more complicated to operate in real life.

However, if my reading of WR box diagrams is right, and I'm aware that this dosen't outline the locking, I don't see many cases where you would not set the points walking one way along the frame, and the signals the other, so when the train passes, everything is restored walking one way along the frame.

(I say this assuming Penzance has sequential locking, but I don't know for sure, since I suppose the installation of colour lights might have affected things) Log in to reply |

Penzance doesn’t with it being colour lights that automatically return to red with the passage of trains.

I reckon I could work 8 or 10 boxes without needing to think about it or even look at the levers back in the day. Learning takes a while of course (I recall the regular signalman's "Thank ****** for interlocking" once, as I grabbed the facing points lever the train was passing over). Most mech boxes had various little wrinkles you needed to get your head around, sequences that didn't make sense unless you realised the history that led to them being like that. On the topic of historical developments remaining in the locking and responding to Stephen Fulcher, would they have gone to the trouble of removing existing sequential locking from PZ when they installed colour lights? Or were the alterations so fundamental that they needed to completely relock the frame in any case? Log in to reply |

I suspect it would have been removed when the line to Long Rock was singled and Ponsandane and Long Rock boxes abolished as that was a major locking alteration. Some semaphores were retained at that time, but the sequential locking would most likely have been done electrically on the lever locks rather than mechanically by then.
