“LINES” (Linear Marks, Strips, Railroad Lines, Telephone/Electrical Lines, Line ups,…)

I fell in love with the BTS Skytrain in Bangkok- the trains are so well organised, the stations are super convenient, sorted out and it is very easy even for a non Thai speaking person to figure their way out.. 
All we had to do was go to the machine on the wall, pick the destination, drop in coins to that total and pick up the ticket [ which was a black circular coin or a squarish one] and get going..
