I wonder how that happened?

There were some interesting entries for East Croydon to London Bridge
services this morning. First Capital Connect's emergency service from
Brighton to City Thameslink was being listed fine, but Southern's service
not quite so well. The Three Bridges to London Bridge service was being
listed three times. Once as a cancelled service (presumably the normal
timetabled service) and twice for what was presumably meant to be the
special service. The East Croydon to London Bridge slow service was
likewise being listed three times, one the Tattenham Corner cancelled
service, and the other two with the Tattenham Corner to East Croydon stops
cancelled but then running fast to London Bridge. Having corrected it to a
slow stopping service the destinations became variously New Cross Gate,
Sydenham and the truly inspired Bricklayers Arms Junction (might have just
said Bricklayers Junction, either way it wasn't terribly helpful). They've
settled on New Cross Gate now (the London Bridge stop showing as timed at
0.00 and cancelled) so still not right.
