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 perceived that to express those impressions, to write that essential book, which is the only true one, a great writer does not, in the current meaning of the word, invent it, but, since it exists already in each one of us, interprets it. The duty and the task of a writer are those of an interpreter.”
—Marcel Proust (1871–1922)
“It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys.”
—Emmuska, Baroness Orczy (1865–1947)
“I met a Californian who would
Talk California—a state so blessed
He said, in climate, none had ever died there
A natural death, and Vigilance Committees
Had had to organize to stock the graveyards
And vindicate the state’s humanity.”
—Robert Frost (1874–1963)
