Has anyone got a better method?

Does anyone want to share their own experience with this stuff?

It should make fishplate greasing a lot easier, and with fewer people. Drawback is that you have to do it more often.

I'm from the Yorkshire Wolds Railway near Driffield in East Yorkshire. We will soon be relaying 'the next field' from our existing site in the direction of Wetwang.

The next field is one of only two in a couple of miles where the old formation (compacted chalk) has been excavated & the field has been returned to arable crops. The others are grasses for grazing, being a few inches of top soil over the formation, so much easier.

As part of our grant application we have planned to...

Track formations - to excavate or not?]]> 3 Mon, 29 Aug 2016 19:33:01 +0000 https://www.national-preservation.com/threads/lineside-clearance-questions.39145/ https://www.national-preservation.com/threads/lineside-clearance-questions.39145/ invalid@example.com (TonyMay) TonyMay
Does anyone want to talk about lineside clearance? In particular what's the best way to clear heavy shrubbery? What equipment do you need? How much does it cost? How many people do you need? How fast can a team clear the lineside? What's the best way of keeping it down once it's been cleared? How does clearance affect the ecology?]]> 20 Sun, 28 Aug 2016 00:30:46 +0000 https://www.national-preservation.com/threads/embankments.10768/ https://www.national-preservation.com/threads/embankments.10768/ invalid@example.com (pseudonym) pseudonym 26 Tue, 05 Apr 2016 20:57:06 +0000 https://www.national-preservation.com/threads/clearing-old-culverts.685168/ https://www.national-preservation.com/threads/clearing-old-culverts.685168/ invalid@example.com (gwilialan) gwilialan It looks like this area doesn't get much attention bit hopefully someone can help...

OK Lads and Lassies, a challenge for you. I need to clear a variety of old culverts that have probably not been cleared for forty years or more while the trackbed was unused. Now we are at the point of clearing the trackside before opening our new extension I keep finding more...

The problems I have are:-
