In 2019, a few months before the pandemic first broke out, we took a trip to the UK. I got to ride the excellent British rail roads several times. All the trains I rode were electric, fast, convenient and smooth. London has 4 or 5 major rail stations, with connections to locations throughout the UK and France.\n\nI rode from Heathrow Airport to London by the Paddington Express, that goes ~40 minutes between the airport and Paddington Station. I took a taxi from there to King's Cross Station, the building with glass dome entrance and tan brick building. On the right (red brick) is the equally large St. Pancras Station, where you can get the Channel Tunnel train to France.\n\nAt King's Cross, we caught a train to York, about 2 hours north. The train, run by the Grand Central Line, was sleek & modern.
