I would like to know:

- the power in hp of the S7 Tube Stock

- the power in hp of the 1972 Tube Stock

- the top speed of the 1972 Tube Stock

- the number of seats on a 5 car Class 378 London Overground train

- the power in hp of the 1992 Tube Stock

- the power in hp of the DLR B2K Stock

- the power in hp of the 1973 Tube Stock

- the top speed of the 1973 Tube Stock

Please find the information you requested below:

Fleet	Power in HP	Top speed
1972 Tube Stock	Continuous running rating 52KW x 16 = 832KW x1.341 = 1152.71 HP   One hour Running rating 79KW x16 = 1264KW x 1.341 = 1695.02 HP	45 Mph
1973 Tube Stock	Approx. 1860 HP	55Mph (Max Line Speed is 45Mph at a limited number of track sections)
1992 Tube Stock	Central line motors are rated to 54kw (1 Hour), hence in very simplistic terms, the total power output from traction motors would be: 32 motors per train x 54kW each = 1728kW x 1.341 = 2317.2 HP	Not required.
S7 Tube Stock	Each motor is 65kW we have 4 motors per car so 1820kW on an S7 train	Not required.
DLR B2000	The B2007 traction motor has a power output of 98KW based on continuous running duty, a B2007 vehicle has 2 traction motors, hence a power output of 196KW, this equates to 263hp   The max power output of a B2007 traction motor however, is 396KW, which equates to 792KW per vehicle, converted to hp is 1062hp per B2007 vehicle (max).	Not required.

The number of seats on a 5 car Class 378 London Overground train are as follows:

• Seating capacity: (Number of full seats per train) 186
• Seating capacity: (Number of tip up and perch seats, excluding wheelchair spaces) 84
