Trivia: Bus route that goes over the most level crossings?

What bus route in the UK goes over the highest amount of level crossings? The most that i can think of are the Compass Bus routes 166/167/168 which are the - Lewes / Hassocks / Burgess Hill / Haywards Heath - area rural routes which go over four level crossings in total. There must be some others as well that go over quite a few level crossings. What bus routes can you think of that go over a high amount of level crossings?

Go North East's 434 in Northumberland, linking Bedlington Station with Linton via the Cambois coastline.

- Ellington Road, A1068 (decommissioned)
- North Seaton, Ashington
- Marcheys House, West Sleekburn
- Winning, West Sleekburn
- Cambois
- North Beach, Cambois

Although it doesn't cross it, due to its position the level crossing at Bedlington Station will delay the 434 if activated. It also comes into the same proximity to Linton level crossing.
