RTT links sometimes 404

[Gaelan]

Got a report today of the RTT link leading to a 404 for 1B70, the 04:54 Inverness to Edinburgh via Aberdeen - today it was cancelled short at Aberdeen ("speed restriction because of high winds"). The bug reporter seems to have been given a link involving the UID O23967.

When I tried it, however, everything worked fine - we linked to the RTT page for the UID W54282, which led to the RTT page for a VSTP planned schedule from Inverness to Aberdeen (not Edinburgh). W54282 also appears to be be the long-term UID used for 1B70 on "normal" days. This is also the UID encoded in the RID, 202401298754282.

So it sounds like Darwin briefly called it O23967, before switching back to W54282? Did the VSTP exist the whole time, or did it the Darwin UID get changed back when the VSTP got created?

Not sure if there's a good way to handle this.
