<p>A Porterbrook Partnership is an evolution on traditional lease types 
(dry, soggy, wet). Under a partnership lease we will deliver additional 
services which can be bolted on to existing leases and which can grow 
over time. </p>
<p> Typical services include Level 1-4 maintenance, heavy maintenance, 
digital services, engineering services, embedded support, maintenance 
optimisation, match funding and the taking of performance risk. </p>
<p> We now have five partnership leases in place with a range of Train 
Operating Companies. The first was our Class 170 lease with Northern, 
where together we improved reliability to such an extent that the fleet 
won a 2019 Golden Spanner. </p>
<p> Our most recent partnership is with South Western Railway on our 
Class 458 fleet, where we have agreed to take on responsibility for the 
performance of these trains and support South Western Railway as they 
transform South Coast and long-distance services.</p>
