London Transport Museum are running three special two hour heritage train journeys from 9.10am starting at Northfields . I was lucky enough to travel on the art deco 1938 Tube train a few years ago and it's a real nostalgic treat.
"The highlight of the day is when the 1938 Tube train will run from Hatton Cross taking a left turn down to Heathrow Terminal 4 where it will then carry on to Terminals 1, 2 and 3 and Terminal 5, this is known as the 'Fish Hook Move'."
It sounds like it will be a great journey and likely to sell out quickly.
The 1938 Tube stock was one of the last units to run in regular London Underground service until 1988 (just in case you wonder why there are a lot of 1970's and 1980's ads in the cars). Tickets are £25 for adults and £15 for children £15.
