I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
The Lincolnshire Wolds Railway at Ludborough runs most Sundays during Summer and on other days for special events.
There are plenty of fields entrances around to park in around the place so its easy to find somewhere to start from.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/08/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
