I have noticed a wide range of signalling. Some pass through with a minimum of horn blasts and those are short "toots". The other extreme are those that seem to just keep blasting away. I wonder if the "blasters" are those who have had accidents. It must be a terrible feeling to see some one or something on the track and not being able to avoid a collision. Any engineer who has experienced this is probably going to be heavy handed on the horn.
