I live near where the Cross Country trains operate, and although some 220s do go along the Rivera line, most are 5-carriage 221s. The class 220s mainly serve the Reading to Newcastle or Bournemouth to Manchester services
I did some quick research looking at RTT of Dawlish and it seems to me that its a mix of both on this part, literally almost 50/50. So I don't know about that.
Cross Country try to run the 221's or 220's in multiple whenever they can on the Scotland to Plymouth routes as this is their busiest route. This service used to be supplemented by longer HST's before their withdrawal. Unfortunately as Cross Country still do not have enough rolling stock, even after receiving Avanti West Coast's voyagers, some lone 220's do end up on the route. However most 220's serve the Reading to Newcastle, Manchester to Bournemouth (with 221's) and shorter services to Scotland emanating from Bristol or Birmingham. As I don't have local knowledge on the Manchester to Paignton trains unlike the Plymouth/Penzance to Scotland trains, I looked them up and found that they are mainly served by five car class 221s.
i wish they would add the alp-44 and the Aem-7 if you think about it the scenery on the nec and M&E hasnt changed much since they ran except for the World trade center being built
The AEM-7 would definitely make a great fantrip run or special excursion trip, from Sunnyside to Trenton and the ALP-44 would be great if there were a few scenarios to depict the URHS excursion off the Boonton trackage.
