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.

    Worth noting Railcards give a discount on the Railair buses, still a third off I believe. Found it a fairly good experience myself when I used the service, also got charged the same amount on the day as online.

  • BJ says:

    With the provision of RA3 there is nlw little jusification for domestic flights between MAN and LHR. Before MAN area readers get on my case, I think scrapping them would probably be a net win for you as it would likely stimulate growth of both existing frequencies and new destinations for direct medium- and longhaul flights from MAN.

    • Jill Kinkell says:

      Careful!!! I’m surprised Anna hasn’t commented yet!

      • BJ says:

        Probably too busy sunning herself somewhere lovely. Seriously though, I do think scrapping flights to LHR is the best thing MAN could do for itself.

    • NicktheGreek says:

      Of course this ignores the fact the first direct Manchester to Watford train gets you in just before 2100, otherwise you’re changing trains in MK or Birmingham. And you’ll struggle to catch a train 10-15% of days out of the year due to rail strikes or engineering works.

      People from Manchester needing an easier time of escaping the North, not a harder time please.

      • BJ says:

        I didn’t know that, I assumed most if not all trains to Euston would stop at Watford. I’d scrap the LHR flights anyway, I think it would be a net win.

        • BA Flyer IHG Stayer says:

          All the times I’ve done MAN-EUS on Avanti the train has never stopped at Watford.

          Some of the other routes may but MAN does not.

          You could get off at Milton Keynes then change to another train to Watford then get the coach to LHR or go into EUS and back out to Watford.

        • novelty-socks says:

          I use Avanti to Manchester quite regularly and I don’t think I’ve ever been on a train that stops in Watford. Is this a thing?!

    • Tracey says:

      It would be a net win if they made more services stop at Watford. The change is relatively easy if you are able and without luggage as it is generally from the same platform, but it is still a pain and relies on both services running to time.

    • Mike says:

      I don’t think an unreliable bus from Watford, where practically no trains stop from Manchester, to LHR is a reason for scrapping MAN-LHR flights. What would be a reason is direct MAN-LHR trains.

  • DG says:

    Sadly the one time I tried to use Railair (from Woking) the coach didn’t turn up.

    No information boards, no representative, and mass confusion.

    Eventually a vague indication from a driver of the service running in the other direction that there were traffic issues. Finally showed up nearly an hour late limiting my time in the lounge and no refund.

    I’m not sure how this service could be described as fit for purpose.

    • Alayna says:

      Happened to me. I got a taxi Woking to lhr5. But since then it’s been fine. Nat-Ex finally has the Portsmouth coach back so the RA2 won’t be on my list again. It’s quicker though to do the bus and train.

    • Jonathan says:

      No communication from them isn’t at all good, but unfortunately traffic problems are outside their control a bit like how airlines refuse to honour their EU/UK261 legal obligations at any opportunity, in this sort of circumstance it’s perfectly valid. Lucky the skies aren’t packed like many roads across the world are like that !

  • Hugo says:

    an add on to a SWR advance ticket tends to only be a few pounds as well.

  • Mike Hunt says:

    Gosh what a lot of comments just for a new bus service.

    There weren’t many comments when there was a new Sheffield to Doncaster Airport bus route announced in 2020

  • Stuart says:

    This site allows you to track most buses in real time including RA2.
    https://bustimes.org/stops/40004404140J

    The link above is for the Woking station bus stop (which is mostly RA2). Clicking on the departure time shows the vehicle location.
    It’s a shame there’s not a more user friendly version/app.

  • Stuart says:

    This bus blog summarises a lot of changes (improvements) to buses to Heathrow airport, apparently as a response to the ULEZ charges.
    https://handsbusblog.wordpress.com/2023/08/17/heathrow-happenings/

    The stand-out update relevant for HfP is the new 730 service from T5 to Basingstoke via Frimley Camberley and Bagshot.

    Also the 710 to Chesham.

    A raft of local bus changes which are mostly too detailed for HfP, but noteworthy, are the improved local connections to Staines, Chertsey, as well as some connections between T4 and T5 (route H30), and out to Feltham from Terminal 4 (route H21) for a train connection. Together these might offer better park-and-bus options outside the ULEZ zone (as some comments were inquiring about).

    Inside London there are now the Superloop routes connecting Heathrow:
    SL9 (to Harrow from Heathrow)
    SL7 from Croydon (formerly X26, and before that 726).

    • editingdeluxe says:

      Thanks for the X26 mention, Stuart – didn’t know that had changed (just yesterday it seems). I remember the 725/726 from when it passed through Bexley, where I grew up, starting from Dartford on its way to Heathrow, I think.

    • Brian says:

      “The stand-out update relevant for HfP is the new 730 service from T5 to Basingstoke via Frimley Camberley and Bagshot.”

      This is good to know!

  • Brian says:

    It seems a shame they can’t run an east bound GWR train from Reading to Heathrow going via Hayes and Harlington, yes it would be slower than a new through route, but I imagine at even once an hour it would be popular. Maybe I should start a new company via “open access” – any angel investors about?

    • ChrisBCN says:

      The problem is that it would have to reverse once it’s gone past the Heathrow junction. That would mean it has to cross the other tracks, stopping other trains and reducing capacity (and there isn’t spare capacity). Adding one train an hour would mean you would have to cancel several others (in both directions) an hour.

      The other option would be to build a dedicated track from the west, which is what is proposed.

      With regards to investing, let me tell you where I am – I’m out.

    • BA Flyer IHG Stayer says:

      An open access operator still needs the train paths and platforms to operate on and from.

      And an additional complication here is that Brian Trains Ltd would need to negotiate (and pay for) the use of the privately HEX owned tunnels and platform infrastructure as well as on the National Rail lines (and pay their access fees as well)

      Brian Trains Ltd might get the former but not the latter or the latter but not the former or get both but the train paths don’t coordinate so you have long delays switching between the lines extending journey times which then make you less attractive to passengers. And you could get paths during off peak hours but not in the peak limiting your opportunistic to make money.
