> Is turning the lock really that different to pushing a button? I don't know what type of hypothetical disability the person above means, but I know the problem of round doorknobs and gloves so I suppose something like that? But a horizontal sliding lock as seen on many types of bathroom stalls already should be similar enough that anyone who can push a button in the right direction can also push these in the right direction However, does a mechanical lock glow and look fancy when you can sell your electronic high-tech locking system to the train manufacturer??
