Hi llamalord,
In UK we have railways not railroads,
and yes generally speaking the left hand track (If you are facing the front of the train) is the one which trains run on. We used to have railway stations, but nowadays for some reason we have TRAIN stations, I think that name has migrated here from your Country.
BTW Our roads, apart from motorways, are very narrow because they are so old and mostly built in the days of horsedrawn traffic. Motorways are very new to the UK, I can remember the first one being built in a blaze of publicity around the early fifties.
Another big difference between UK and USA is our towns and cities. Here they just happened
with no special plan, unlike yours where they are often laid out in blocks with right angled junctions and straight roads. I will conclude by saying that I would love to be able to walk on the ceiling if I could!!! However I usually walk on which ever side of a corridor is free.
