Andy Goodwin holds the surveying staff for Dave atop one of the many marker posts. Spaced at ten metre intervals and positioned an exact distance from the intended line of the railway, these posts will provide height information for the people actually levelling and ballasting. Therefore their height has to be measured accurately, and then a sighting crossbar can be attached to each one at the correct position. Rick Beton | |
