He stepped out into the void and fell to the ground.
His guide dog refused to move.
The fellow reports that no PA announcements drew attention to the fact that Leura had a short platform. Black mark for the guard.
More modern trains such as T, G, and OCSAR sets distinguish stations with short platform with the abbreviation "SP4", etc. Obviously these are not much use to blind people, though not of course to his dog.
Fortunately, the Guard in presumably the rearmost carriage saw the accident and was able to help. The passenger was not really harmed.
IIRC, long trains at short platforms generally stop with the the front cars off the platform, and passengers are advised to travel in the rear cars. However, if the driver forgets how many car are in the train, he may stop with rearmost cars off the platforms. If such a mistake is made, the guard should ask the driver to move the train forward.
Lengthening platforms is expensive, particularly if there are masts, piers, narrowing track centres, etc. in the way. Leura is an island platform, and possibly a station with lower patronage.
Short Platforms are well documented on pamphlets available at stations. What about on 131500.com.au.
