i think they should use the put the GWR class 800/802 and the Class 387. Both are EMU’s and have been on the GWR mainline since about 2017. And if you want to do a route it shows an option weather to choose the 166 or 387. Or 800 or 43(Hst).I think they would be a great addition to the route.They could also add the class 345 in tfl rail livery to go between London Paddington and Hayes & harlington because they haven’t built the platforms for them to go to Heathrow yet. Here are some pics 387 142 at London Paddington 387 133 at didcot parkway Class 800 at Bristol temple meads Class 800 Class 345 at Hayes & harlington platform 5(terminus platform) GWR is going to take over the Heathrow express services(or they already did) they are going to replace the 332’s with 387’s.The 387’s are going to have a first class section and they are going to add extra baggage areas.
