"From 2 January 2011, the minimum balance on your Oyster card before
it is automatically topped up is changing from £5 to £8. This is to
ensure that all customers with Auto top-up will always have enough
credit on their cards for any journey they wish to make."

Slightly misleading original subject line though - this is in relation
to *Auto* top-up, and is not to be confused with the £5 minimum top-up
rule at Tube station ticket offices (which seemingly isn't always
enforced)

Yes, I unfortunately missed out a word - now included.
