Heathrow Express 387 130 at London Paddington 

class 387 looking fresh in heathrow express

Bombardier Transportation (taken over by Alstom) could of manufactured the Class 387s for Heathrow Express to replace the Class 332s. Instead of modifying the Class 387s which GWR now has 33 Class 387s. Maybe Heathrow Express could inherit the Class 379 Electrostars from Greater Anglia. And some Class 379 to GWR. Say like 15 Class 379 (379001-379015 to Heathrow Express and 379016-379030 to Great Western Railway). As Greater Anglia is to introduce the Class 720s in service on the West Anglia Main Line and Class 745/1 have replaced the Class 379 on Stansted Express. en.wikipedia.org/wiki/British_Rail_Class_379 en.wikipedia.org/wiki/British_Rail_Class_387
