A similarity - being next to something much larger than you whizzing by at great speed. It doesn't have to be 125 mph - a 30 mph train would probably do. That is similar, yes? Therefore it is an analogy.
An analogy does not have to replicate every aspect of the thing being modelled. But for the motorists who don't see the problem 'because I didn't hit you, did I?' - the analogy may help to give them some idea of the things wrong with close passes. No one said it was a statistically accurate model - it is a tool to help the unthinking think a little.
In fact, it can be used to help them think about several aspects - imagine you're walking between the yellow line and the edge of the platform...
- doesn't that wall of steel whizzing by feel threatening?
- what if you trip over as the train is whizzing by and fall into it?
- what if you don't hear it coming (in cycling terms, because of the noise of other traffic) - might it make you wobble a bit as you walk, or jump
- if it does make you jump, what would happen if you flinched towards the train and it hit you?
- if it makes you fall the other way, you're better off than the close-passed cyclist because you will only fall onto a flat platform, not under the wheels of a following vehicle
