Wait, the Monks and the Woodside were open
at the same time? The gods of Urbex must have been smiling upon you that day, I've only ever seen one or the other accessible.
There needs to be a Three Tunnels Challenge. Reach the far end of the Woodside, Monks Ferry and Haymarket tunnels and return to McDonalds in the retail park, all in under 1 hour. I'll give a prize for the first person to post timestamped photos!
Yeah I'll definitely take someone with me cheers
Take about six people! That place is smackhead central, sharps bins and stuff everywhere. Tread softly and carry a big tripod.
If you get there and find both tunnels greased up and inaccessible, it's fairly easy to get down onto the dock branch right next door and have a nose at the Haymarket Tunnel. It's a very photogenic structure and still has tracks intact, which make for interesting pictures.
