Hey Everyone,

Having just been issued a £20 Penalty Fare demand from DLR officials,
I wondered if anyone could let me know whether the The British Rail
(Penalty Fares) Act 1989 applies here? If not, if you could possibly
point me to what act does apply?

Many Thanks!

As for using your Oyster card, how to use it is laid down int e
Conditions of Carriage, http://www.tfl.gov.uk/assets/downloads/May2007.pdf.

"6.6. Using a season ticket on your Oyster card
6.6.1. When you use London Underground and National Rail services, you
must touch your Oyster
card on the card reader at both the start and the end of your journey.
If the ticket gates at stations are
open you must still touch your Oyster card on the card reader."
