Morning again,
Overground trains run at about 15 minute intervals during the day, 7 days a week between the two stations with a journey time around 52 minutes.
Thanks Mike, I didn’t realise there were Oyster readers on the LNWR platforms and I went through there on Tuesday (as you know I like to get around!) – guess they’ve done a “Waterloo” where the reader isn’t in an obvious place like on the Waterloo and City line.
Journey time on the LNWR is much quicker at about 20 minutes.
Chris
