<p>Reducing the maximum speed of trains from 360km/h to 320km/h would result in trains
taking longer to complete their overall journey. This means that, unless we buy more
train sets, we will not able to run as many train services on HS2 and therefore capacity
will be reduced.</p><p> </p><p>In my previous answer [HL5562], reduced capacity was
also in the context of running tilting trains at 300km/h on the HS2 network. Mixing
tilting trains running at 300km/h on HS2 with non-tilting trains running at 360km/h
would also reduce capacity because it would reduce the number of train paths available
per hour. Furthermore, the response to our market sounding of rolling stock manufacturers
has indicated that <del class="ministerial">titling</del> <ins class="ministerial">tilting</ins>
trains offer reduced seating capacity per train set compared with non-tilt.</p>
