I’m not against advertising on public transport. It brings in much-needed revenue and helps subsidise services.
But it shouldn’t be intruisive.
Bus and tram passengers have had to get used to ads on windows of vehicles over many years, but it’s only in the last couple of years that it’s become prominent on trains. It seems to be applied with a semi-transparent film.
Generally they seem to aim for some, but not all, of the windows along the side of a carriage… and not every carriage, so as with buses and trams, some windows are left clear.
But this still results in some visibility problems.
Looking in from the outside it’s very difficult to see inside, meaning staff (including PSOs) may be unlikely to spot issues inside the train. It also makes it more difficult for passengers boarding to identify and avoid the more crowded parts of the train. It might be a tad better at night, but during the day you basically can’t see in.
Looking out from the inside of the carriage is a mixed bag.
Viewing across from the other side of the carriage, it’s actually not bad, at least in daylight. Outside scenery, including important things like station signs, are quite visible.
But up close, it’s not as easy. It can be difficult to focus on things outside, at least if they’re some distance off, which may make some signage difficult to read.
To compare to a clear window, you can kind of see the effect of the film in this photo, though the way the camera has focussed doesn’t exactly reflect what the eye sees.
Objects very close to the window, such as the station signs in the underground loop, are still very clear — but at most stations they aren’t that close.
Those who have real problems seeing out or knowing where they are will want to aim for windows that are unobstructed.
But this may not be an option during peak hour, and really, government and operators should ensure that passenger visibility (both in and out) of trains (and trams and buses) is better than it is with these ads plastered over them.
