A question: in the pic in the following link, any idea what the purpose of the small sloping ramps on either side of the boardwalk between the rails is?

Hi Nigel,

Assuming that they aren't covers for pipes or cables my best guess would be to deflect anything hanging too low underneath the train upwards rather than having it meet the straight side of the crossing ( which would result in a lot of mashed up wood and maybe a derailed train ).

Hi Rob

That was the feeling on Geograph. But I wondered if there wasn't a different reason so thought I'd ask the experts :)

The one thing which makes me wonder is that the boardwalk looks only slightly higher than the rails, so if anything dangling down could hit the boardwalk then it would probably hit rails crossing as in a turnout, which wouldn't be a good idea.

Cheers
Nigel

Hello Nigel
Yes, they are to deflect low hanging couplings. I asked that question of my Dad one time I joined him on a walk along a line.

I asked that very same question about hitting closure rails on turnouts and I think he was trying to explain that if they hit a closure rail it would be at an oblique angle and would partly deflect the coupling whereas on a crossing it is straight on and would be harder impact.

That was a conversation from the mid 80s walking between over the Bog Hall crossing at Whitby, so an old memory.

PS I also asked why when the coupling wasn't long enough and I think he indicated that some screw couplings, when fully unscrewed would go down to that height.

Hope that helps.

But looking at that bit of wood in the photo, I think I know which will come off worse if hit by a coupling at 60mph. :?

Come to think of it, AWS ramps often have a ramp on the back, steeper than the main ramp (unless bi-directional in which case both are shallower). Not always though.

Yes, I think you're right about the wood, mind you if it's recycled sleeper/timber it could still make a mess- land splinters in the flangeway and even dent the couplings.
