60kph in the lead-up heading south through Cotton Vale/Thulimbah/The Summit and through the level crossing (there’s a blind 300m radius curve between The Summit station siding and the level crossing). It was 80kph on the straight afterwards through Glen Niven (towards Stanthorpe). But QR has lowered the speed limits on most unprotected level crossings in the area to 25kph (noting the one across the New England Highway is not unprotected).
The track is almost dead straight through the 60kph zone, but is maintained to a low standard (bad ballast, 50% timber sleepers etc.), so even in the absence of level crossings, there are definite limitations. In the context of track that is effectively only used once or twice a month by a steam/diesel operated tourist service, the level of maintenance is reasonable (no freight operates on the line past Warwick; all freight goes south-west to Goondiwindi/Thallon).
But it highlights the risk averse attitude of the organisation. There was no clear rationale to lower the speed limits on quiet unprotected crossings at Cotton Vale, Thulimbah or in The Summit township. They just added those because they could as well.
