@coluber2001,
Oh I do love trains since my early childhood when I use to go to Barcelona to Barraquer Ophthalmologic clinic to save my vision from blindness which I did.
I remember vividly to stay woke at night in my bunk lurking through the window and seeing the lights of far away villages while the train kept on pushing
I have trouble sleeping so I cannot afford to do the trans-Siberian train but that would be a perfect adventure. The oriental express is to well know and I rather avoid the typical tourist company.
USA is a bit to far but I would love to do a Coast to Coast also.
Advice on other routes is welcomed!
