I love trains. Always have. And the Tube! And the London Underground Map too. One of the most beautiful designs in the world!! At least it was until the late 80's when added the jubilee line etc, which began to unbalance/crowd the spaces.
Love long train journeys, through Greece and Turkey, and along coastlines, and along the backs of houses so can see all the usually hidden parts of them ( all the rubbish and mess of backyards!)! ! And stations for waiting and watching people, and drinking coffee and reading frivolous magazines with passionate attention, and departure boards, and sleepy station concourses in the south, along the mediterranean, where can congregate with wine and spliffs and guitars and no fixed destination, and hang out till dusk or later, even sleep next to the station buildings, and nobody comes to move you on. And watching landscapes flash past with no need to step into them, and scenes out of stories pop up and get left behind, and not having to do anything but watch and think.
And the swaying movement, the smooth glide, the irrisistible advance, the absence of traffic lights!! How safe they feel.
Don't know a thing about them, tho was impressed by the information, gleaned from a childrens science programme my son watches sometimes, that the wheels on TGVs/superspeed trains are turned by electromagnetism. I didn't know that!!
I prefer older trains tho where can open the windows, and stretch out, and get snug and picnicky and owner-ish with six seats in a compartment!!
