Don Wood's NY&LB book has details on Brielle. Interesting story: Money was missing from the till on a regular basis at Brielle, and the agent was fired for theft. When the station was torn down, shredded money was found in the beams and joists, stolen by rats and mice to make nests. The agent was paid back pay from the time he was fired, several years worth!
Avon closed after 1963. It was so close to the Belmar station, it became a skip-stop station, used sparingly during commuter runs. I lived next to the old Sylvania Ave. wooden bridge back then, and loved to watch the eastbound trains getting started from Avon. Nothing like some diesel exhaust blasts standing on that bridge!
