Ok. If we're going by if all rolling stock was built in the last 20 years; Modern UK routes: - Southeastern High Speed (set 2020) Period UK routes: - Northern Trans Pennine (set 1983) - Tees Valley Line (set 1989) - West Cornwall Locals (set 1950s-1990s) - Great Western (set 2016-ish) - Cathcart Circle (set 2011+, probably 2019) - East Coastway (set 2018) - Isle of Wight (set 2011+) - Bakerloo (set 2020) - West Somerset (set 2017-ish) I'd say all but 3 are actually period routes. If we go by if any rolling stock was built in the last 20 years, then move East Coastway up to modern routes. The EWS/DBCUK examples of the Class 66 were built 1998-2000, therefore not qualifying the respective DLCs. My point was if you say "modern route" I take that as a route set in the last 15-20 years, hence the original list I still stand by.
