10:21 East Grinstead train from Victoria (Clapham Jct 10:28, East Croydon 10:39), arriving Upper Warlingham at 10:51. If it's more convenient the Caterham section of the stopping 09:54 service from London Bridge crawls into Whyteleafe at 10:44. Starting from this station is covered in the directions, but it would be more sociable to meet the others at Upper Warlingham (a four-minute walk, signposted). Buy a Zones 1-6 Travelcard or use your Oyster card.
This year is the centenary of the RAF and this is being celebrated at events like the Biggin Hill Air Show with flypasts by Spitfires and other historic aircraft, as well as the usual displays by the Red Arrows, etc. There would be better views of all this from the Hayes-Knockholt walk but Network Rail have thoughtfully scheduled engineering works on both these lines, so that's a non-starter. It still means that you won't have a simple return journey by train but there are many other possibilities from Hayes, including:
- A rail replacement bus to Lewisham at xx:05 & xx:35
- A 10-minute bus ride to Bromley South (138, 2/hr & 246, 1/hr)
- A 25-minute bus ride to East Croydon (119, 4/hr)
- Divert to New Addington for a shorter walk and Tram to Croydon
