Dear Ben Jones 
Information request 
Reference number: FOI2021/01235 
Thank you for your email of 22 August 2021, in which you have requested the following 
β€œAt the Ouse Valley Viaduct site in West Sussex (VTB3 142) there is signage stating 
that the flying of Drones/UAV's on/over the land is  "strictly prohibited" and anyone 
doing so will be "reported for prosecution" and "subject to civil legal action"  
The information I request is: 

1) Who owns the land the Viaduct is on, including the public right of way that runs 

from Borde Hill Lane across the land and under the Viaduct.  
2) Are these signs Network Rail's? If so what legal basis is there to "prohibit" the use 
of the airspace around and over the Viaduct as long as flights are conducted in 

compliance with the drone code, the Air Navigation Order and CAP722?  
3) In your response to an FOI request with the reference FOI2021/00001 you state 

the information on your website in relation to references about flying over the 
railway is a criminal offence is incorrect and should be removed, can you confirm if 
the similar references on this page (

have just been overlooked?” 
I have processed your request under the terms of the Freedom of Information Act 2000 
The land the viaduct is on, including the public right of way mentioned, is owned by 
Network Rail. However, the signs you refer to are not ours, but are instead situated on 
Network Rail Infrastructure Limited Registered Office: Network Rail, 2nd Floor, One Eversholt Street, London, NW1 2DN Registered in England and Wales No. 2904587 

private land which adjoins our property. If the land is registered then it is possible that you 
might be able to find further information about its ownership at the Land Registry.1 
It may also be useful to look at the drone safety information on our website page here: Drone 
safety and the law - Network Rail 
You can also refer to the Air Navigation Order (issued by the CAA β€“ Civil Aviation 
Authority) which has the last updates for UAV (Unmanned Aerial Vehicle) operations in 
the UK. Below are a few more websites which you may find helpful.

Unmanned Aircraft System Operations in UK Airspace β€“ Guidance ( 
The revised Air Navigation Order | UK Civil Aviation Authority ( 
Finally, regarding the references on our website page, I have consulted with the relevant 
colleagues in our drones team and I can confirm that certain information on the website 
page are out of date. New regulations in relation to drones came into place as of 1 
January 2021 and as such we are now working to change the wording on our webpage to 
reflect these changes. There are no specific regulations that have specifically been written 
for railways.  
I hope this response is helpful. If you have any enquiries about this response, please 
contact me in the first instance at xxx@xxxxxxxxxxx.xx.xx.  Details of your appeal rights 
are below.

Yours sincerely
