I lived in Manor Park last year. Yes there is a bus to the train station. You have to get the 36 which goes to the town centre and get off about 15 mins after leaving MP. Really easy as i think buses run at least once every 30mins if not more frequently. I think a single was about £1.20. I actually bought a years bus pass which was £120 and came in handy on rainy days! Think the bus pass has gone up to £135 this year, but it is still well worth the money!
