New RailAir route from Watford to Heathrow, and improved Woking times from today

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

In 11 years of HfP we’ve never looked at RailAir, so I thought the launch of their third route – RA3 – and improvements to the Woking service from today were a good excuse.

If you travelling to London Heathrow by rail from central London, you aren’t short of options. As well as the Piccadilly Line tube trains, you now have the Elizabeth Line, capable of whizzing you from the West End, East London or even Essex directly to the airport. The Heathrow Express continues to operate from London Paddington every 15 minutes.

RailAir coach

Great news if you live in London. If you live to the west of Heathrow, it’s a different story. There is no direct rail link heading west from Heathrow – even though platforms for such a service already exist at Terminal 5 and have done since the terminal opened:

Heathrow Terminal 5 unused national rail platforms

In theory a new rail link from the airport, using these platforms, would join the Great Western line between Langley and Iver. The chance of this getting in done in my lifetime appears slim.

With no direct link, the RailAir ‘luxury’ coach service, operated by FirstBus, fills the gap.

Where does RailAir run?

Ignoring the new route for a moment, the two existing RailAir routes are:

  • RA1 – Reading railway station to Heathrow Terminals 2, 3 and 5, 40 minute journey time
  • RA2 – Guildford and Woking railway stations to Heathrow Terminals 2, 3 and 5, ‘under 1 hour’ from Guildford and ‘under 40 minutes’ from Woking

RA1 runs virtually 24 hours per day, from Reading at 02.40 to 23.05 and from Terminal 3 at 04.05 to 00.15. Buses run every 30 minutes except in the late evening.

RA2 runs from Guildford at 02.30 to 00.00 and from Terminal 3 at 03.58 to 00.28.

Woking services improve from today, 20th August

There are changes – improvements, actually – on the Guildford and Woking route from today.

Guildford services will remain hourly, as previously, but the service from Woking will operate every 30 minutes. This means that some services will start in Woking whilst others will be a stop on the Guildford to Heathrow route.

What is the new route launched last month?

RailAir now also operates from Watford.

Buses go from Watford Junction and Watford town centre to Heathrow.

Route RA3, as it is known, runs from Watford Junction between 03.55 and 23.00. Return buses from Terminal 3 run between 04.35 and 23.40.

The RailAir website has full timetable showing all intermediate stops.

What facilities do you get?

I’ve never used RailAir, but the website advertises free wi-fi and free USB charging. Some seats are in blocks of four with a central table, which is handy for families.

It also advertises a ‘VIP Lounge’ at Reading – this is described as ‘spacious’ and offering ‘complementary hot drinks and newspapers’.

All coaches are fully accessible for wheelchair users.

How much is RailAir?

It’s not cheap, to put it mildly.

Bought online in advance, a single ticket from Reading is £22, with a return being £30.

A single ticket from Guildford or Woking is £9.50, with a return being £17.50.

A single ticket from Watford is £9, with a return being £18.

There is a premium if you attempt to pay cash on the day.

The cost of a child ticket varies. From Reading, Guildford and Woking they get a discount of roughly 50%, but you may still find an Uber is cheaper for a group. On the new Watford route, children under 16 are free.

If you have more than two suitcases per person there is an additional charge.

You need to select a particular service when booking. You are guaranteed a seat on this service, but if your flight is late you can take any other service on the same day, subject to a seat being available.

RailAir tickets are available as an add-on to National Rail fares.

Any thoughts?

RailAir is something I have never tried. If you are a regular user and have any feedback or tips, please leave them in the comments.

    Have used it for both Reading and Woking always been impressed. Funnily enough I’m using it in Nov to Woking and the timetables were showing a two hour wait at LHR- clearly that’s wrong given the above.

    Not sure when the Woking service became operated by First. Back in the day it was operated by Speedlink (remember them!) branded as rail air and then National Express. Last time I used it in early 2020 it was still National Express. I might be wrong but Speedlink (branded as Jetlink) also operated Stansted- Luton- Watford- LHR in the late 90s also.

    The Airline from Oxford Bus Company is another impressive operation.

    • Mark says:

      First started RA2 before the pandemic but went from Guildford to Heathrow via Wisley & not Woking.
      National Express stopped when the pandemic started & never returned however RA2 already by then served Woking.

  • ChasP says:

    That brings back memories
    Nearly 40 years ago with three heavy cases and a pregnant wife at Woking
    Humping 3 suitcases one by one up the stairs then one by one across the bridge and down the other side and dashing in the rain to catch the coach

    I assume it has improved as I believe there is now a lift but its still not a pleasant experience with luggage

  • youngtraveller says:

    Used the Reading service plenty of times coming from Bath, Bristol and Cardiff by train. Very convenient and when I took it was never busy or full, even during the Christmas holidays. And they drop you just at the entrance of T4 and T5 as well as the bus station of T2&T3. I remember taking it to T4 but I could be wrong as the article points out they only take you to Terminals 2, 3 and 5.

    • Johnny5a says:

      T4 is not served by Railair anymore.

      • G says:

        Just get a tfl bus to Richmond pools in the park – i think its the 690 bus. Goes from the stand just before railair direct to t4 via a few internal stops (only used by lhr staff anyway).

    • acewoking says:

      They do not stop at the Central Bus Station. This has also recently changed and caught out many people including me. They stop outside Terminals 2 and 3, and 5, but not the Bus Station. And also not Terminal 4, you have to get the free Tube shuttle to one of the other terminals.

  • Johnny5a says:

    I’ve used Railair from Reading, I’ve never had an issue. It is useful for T2,3,5 (not T4). The Railair doesn’t serve T4, you’ll need to take the HEX/EL free transfer.

    Rob, you omitted to say Railcards (apart from 16-17 Saver and Network Railcard) can be used to obtain a discount.

  • Brussel Sprout says:

    The problem is that it is hideously unreliable. I am writing from this mornings 0528 service from Guildford which has just left Guildford at 0544. You always need to allow an extra hour if you have a flight to catch to take account of their frequent problems (several services were cancelled Friday morning for example). Once the coach broke down just outside Guildford so I got my other half to pick me (and the other 2 passengers) in the car. They would not give me a refund because the next bus in 1 hour would have picked me up! Total joke of a service but better than nothing. Note there is no onboard toilet which can be a bit much on a 2 hour journey after a flight..

  • John says:

    There is a new bus 710 from next weekend, which goes from Chesham and Amersham to Heathrow twice in the early morning in one direction.

  • Franchie says:

    Look at their Twitter feed if you want to see how reliable this service is. 3 cancellations to Guildford in 1 day

  • Grumpy Chicken 81 says:

    It came as news to me that there wasn’t a railair link from Watford Junction to Heathrow, I recall using it once way back in 2001, got stuck on the M25 and decided in future I’d just take the train all the way to Euston and get the tube to Heathrow.

    • Nick says:

      There’s a local bus from Watford, just not an express coach. Will be interesting to see what happens with the new coach, given the bus fare is much lower (£2) and few long distance (Avanti) services call at Watford anyway.
