@notjustbikes I always used ‘commuter rail’ as the English translation for what is roughly ‘suburban rail’ but your post here is making me rethink it
For example I always called the October Railway within Saint Petersburg and the greater NW region ‘commuter rail’ since it runs 6-8 carriage, 3+3-a-row seat EMUs with operating distances of up to 150 km and travel times of up to 3 hours, and like back in my home country, these are used by commuters (bus routes to the stations, train to the city and the metro system — they do not have any park and ride facilities whatsoever) and people who need to get to the city or out of the city throughout the day (starting around 5 and last service being around 24:45)
What would one properly call these?
