Comparison of HS2 and SPR System

Speed and Journey Time Comparison with HS2

HS2: 225mph (362kph) SPRS: 180mph (290kph) RoboCar 200mph (322kph)

HS2: to Birmingham: 48 minutes SPR64 to Birmingham: 42 mins @180mph

HS2 to Manchester: 1hr 10mins SPR64 to Manchester: 1 hour 9 mins @180mph

Service per day: HS2: 19 hrs (6am to 12 midnight) SPRS: 24 hours 7 days a week

Comparison with HS2: Seat/Vehicle Capacity over 24 hours

HS2 at 10x400m 1120 seat trains per hour for 19 hours: 212800 Seats      

SPR Shuttles 230400 seats available+ RoboCar Capacity 

SPRS has a theoretical capacity of nearly a quarter of a million seats per day.

Cost of kWh per passenger (journey London to Birmingham)

HS2 5.3MWh : 95 pence per passenger (100% capacity) £1.19 (80% capacity) £1.58 (60% capacity)

SPR64 : 91 p per passenger (100% capacity - Energy cost per passenger ranges between 91p and £1.02 max

One advantage of the SPR system is that it can constantly adapt to demand. Whilst the energy consumption of an HS2 train remains virtually the same no matter what the passenger levels, the SPR system can adjust and so therefore the cost per passenger is relatively consistent.

These calculations based on the theoretical seat capacity of 400m long form HS2 trainsets, NOT passenger demand

Annual Energy Consumption of HS2 vs SPRS

HS2 annual energy consumption of phase 1 and phase 2a is 1.01TWh annually

Silk Purse Road (seat equivalent running SPR64 shuttles)

From Birmingham daily this would be 41.4MWh

From Manchester daily this would be 97MWh

Annual total consumption = 957.12GWh

Please note that the purpose of this calculation is not to provide detailed modelling of costs but to demonstrate that the SPR System is comparable to HS2, which we believe to be the case.
