Gloucester is the longest continuous platform, Colchester doesn't have a continuous platform as it loses a track in this sort of layout... Although I see that Wikipedia says that Colchester is the longest I'd be quite happy to take that up to debate as it most certainly isn't a continuous platform IMHO▸ (ie, if trains from the up Sunshine Coast were to cross and stop half way between both platforms there'd be about 2 coaches off platform).
Like I said here then?
