It is unlikely that you will need to travel by local train unless you are staying some way out of the centre and are close to a station or wish to visit somewhere on the outskirts where there is a station. If this is the case train travel may be an option worth considering although you are likely to need to connect with other forms of transport at your destination station. You should purchase tickets for train travel prior to boarding a train where possible. Most stations have a ticket office and those without will have ticket vending machines. Oyster Cards cannot generally used for payment of train tickets but Travelcards are valid for travel on trains within the zones the Travelcard covers and can be purchased at the station ticket office.
