People tend to check in during these times:
Turnmill Street side entrance only open 07:00 – 10:30 Mon-Fri
HANDY EXIT: If you're visiting any venues to the north of the station (e.g. Clerkenwell Road) Find the 'rush-hour-only' exit on Turnmill Street to avoid the chaos at the front of the station
Watch out for @FarringdonMouse
Eastbound underground services are on platform 1, westbound on platform 2!
Side exit only opened during peak hour
The left hand pavement on the west side is blocked of. Use the right hand pavement during the works.
Beware the tediously "off-script" announcer at this station who is very fond of the sound of his own amplified voice.
The 18.12 and 18.25 Brighton trains are surprisingly empty towards the end of the platform - worth the walk ;)
First Capital Connect platforms get very crowded in the evening rush hour. Particularly when trains are running late (ie most of the time).
New in; ticket barriers are now active. Side gate is still operational during peak times.
Don't rub *anything* against the tracks. They don't like it.
Wear ear-plugs or noise-cancelling headphones because this station has overly loud and very annoying announcements.
Don't try to exit using an FCC "London Terminals" ticket, the LU staff will kill you, or worse.
One of the very first underground stations. Currently undergoing massive rebuilding works for Thameslink and Crossrail.
Possibly the friendliest underground staff in London. Check out the counter guy, he looks like a 1920s strongman! Sorts your Oyster out no problem! Legend!
Beware the 'amusing' announcements. They are tedious.
Be prepared for First Capital Connect delays and shitty trains.
Walk along the road to Tinseltown and treat yourself to an original American burger and an Oreo milkshake to die for.
The stupid First Capital Connect "Departures" board spends more time displaying (non-)service announcements than actual train times! USELESS!
Appetite on clerkenwell green for yoghurt, granola, banana and honey. Awsome
Do not step on the tracks, ever, they're filthy.
Don't expect any First Capital Connect service to run on time. Expect nothing and you won't be disappointed.
Reopened side door is bloody amazing if you are going eastbound. Don't forget to touch in though!
Use the side exit during peak hours. It's not quite so busy and there are no barriers.
