The interlocking doesn't allow signal T4 to clear towards T6 at Truro without first lowering and clearing Truro crossing. This seems fair enough given how close T6 is to the LC and the possibility of an overrun. It doesn't look like there's any form of approach control/warner route to get around this requirement. Two things though: (a) you generally try to keep crossings down for the shortest possible time, and up trains can arrive at Truro a good 6+ minutes before they're due to leave - do we just bite the bullet and keep the crossing down for a long time to keep the driver on clear signals? (b) if an up train is stops at Truro and reverses (mainly thinking of the unit to work the first Falmouth train of the day, which can shunt via T14), the train can't be signalled into the platform without the crossing lowered anyway, even though it isn't going over it. It seems odd to lower a crossing only to raise it as soon as the interlocking drops out with nothing passing over it. Am I missing something or is this just a real-life quirk of the locking?

It is (was) true to life. If you have six minutes before the train leaves you could keep T6 at danger and raise the barriers after the train arrives and lower again ready for departure Log in to reply The following user said thank you: OJH |

It's accurate. For a train with exceptional dwell time it would be checked at the home nearly to a stand then brought into the platform against a red with the barriers down, then barriers raised. For a train booked to reverse it would equally be checked anyway as the up section isn't being cleared. The reasoning is to guard road traffic against a SPAD given the proximity of the protecting signal as you said. Worksop East had an interesting standing instruction (presumably to mitigate spads) requiring the crossing protecting signal to be cleared, and then replaced to danger when the train stopped in the up platform and barriers raised. Drivers to expect this and check the signal carefully. Exception to this being trains making brief stops. "We don't stop camborne wednesdays" Log in to reply The following user said thank you: OJH |

As the crossing at Truro only leads to the P-Way Depot and Station Car Park they’d likely just pull off and give the train the distant, two bridges available for pedestrians.

Nothing like seeing it in real life years after the sim came out and discovering it actually leads to a dead end/scrap yard/nothing at all, recall one on Sheffield in particular...
