I agree I thought subway in Singapore was amazing last time I visited. What I really liked was the way the carriage always stopped at the same fixed point on platform and they had designated areas for people to stand when embarking. It made the whole process of getting on and off the train much more organised.

Here in Australia trains are no where near that disciplined about where on platform they stop. Carriage doors can be anywhere so basically as soon as train pulls into station everyone on platform surges towards nearest door.

I was in London in January I found the underground there very confusing. I was doing the typical tourist sight seeing thing and was trying to get from Tower of London to the British Museum I knew the stations were on different lines I knew I had to get to the Piccadilly line but there was a lack of detail as to where to change trains. There were voice announcements on trains themselves "Change here for xxx line" but signage was pretty poor.
