RUSH HOUR Trains at Lichfield Trent Valley

Some trains at Lichfield Trent Valley
We see the usual Avanti class 390s and LNWR class 350s, along with the new class 730 on the Cross City Line, and the even newer Avanti class 805 Evero. We also spot a pair of 325s and an unexpected railtour surprise

Does anyone know what that railtour was?
