High Speed pass through Milton Keynes Central on the way to Liverpool Lime Street from London Euston.
post edit: as per comments section, Mr Memory 3.14 reliably informed me this train is headed for Birmingham not Liverpool Lime Street - thanks!
The British Rail Class 390 Pendolino is a type of electric high-speed passenger train operated by Avanti West Coast in the United Kingdom, using Fiat Ferroviaria‘s tilting train Pendolino technology and built by Alstom.
The Class 390 Pendolino is one of the fastest domestic electric multiple units operating in Great Britain, with a design speed of 140 mph or 225 km/h; however, limitations to track signalling systems restrict the trains to a maximum speed of 125 mph or 200 km/h in service.
