Current Rolling Stock
The line is currently electrified with 25 kV AC overhead line as far south as Drayton Park and 750 V DC third rail from there to Moorgate. Services are operated by Class 313 electric multiple units (EMUs), the only units certified for use on the line. In keeping with the UK regulations for trains operating in single bore tunnels, they have emergency doors at the end of each unit, and are also designed so that when operating on 750 V DC the two motor coaches are electrically separate as far as the traction supply goes - unlike other contemporary units, there are no DC traction supply jumper cables between carriages. All Class 313 units operating over the NCL are configured with their Driving Motor B vehicle at the London end, and whilst on DC traction current are electronically limited to 30 mph, which is the maximum line speed on the Northern City Line. All stations are long enough to accept two three-car EMUs.

Famous quotes containing the words current, rolling and/or stock:
“I don’t see America as a mainland, but as a sea, a big ocean. Sometimes a storm arises, a formidable current develops, and it seems it will engulf everything. Wait a moment, another current will appear and bring the first one to naught.”
—Jacques Maritain (1882–1973)
“As artists they’re rot, but as providers they’re oil wells; they gush. Norris said she never wrote a story unless it was fun to do. I understand Ferber whistles at her typewriter. And there was that poor sucker Flaubert rolling around on his floor for three days looking for the right word.”
—Dorothy Parker (1893–1967)
“However low and poor the taking Snuff argues a Man to be in his own Stock of Thought, or Means to employ his Brains and his Fingers, yet there is a poorer Creature in the World than He, and this is a Borrower of Snuff; a Fellow that keeps no Box of his own, but is always asking others for a Pinch.”
—Richard Steele (1672–1729)
