5’s main line testing

(PRM-TSI) Sleeper cars, and 1530115340 for the standard Sleeper vehicles.

The Mk 5s were ordered by Caledonian Sleeper owner Serco, when it was awarded the franchise in 2015 ( RAIL 750).

They are funded by Lombard Leasing and will replace the existing fleet of Mk 2 and Mk 3 coaches, the latter of which are leased from Porterbrook. @Clinnick1
