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.

    Needed to return to Winchester but with late arrival of flight (friend unable to pick me up after delay) I bought railair link (RA2) to Woking and train ticket to Winchester whilst taxiing into T5. You can get the tickets for both on the Trainline app. At T5 the coach pick up point is fairly central within the coach section and a short walk from arrivals. I would agree that the M25 Jct 11-14 is the vulnerable part of the journey but the bus driver skirted past a substantial amount of traffic to keep on schedule.As long as allow for some delay at peak times, it’s a very convenient service.

    Where’s Woking?
    I thought it was a verb.

    • acewoking says:

      25 minutes from Waterloo, 6 fast trains an hour. Plus all the SWR trains from Alton, Portsmouth, Southampton, Poole, Weymouth, Exeter all stop there. So a very handy way of getting from the South West to Heathrow. If the bus was reliable.

  • George K says:

    Public transport connectivity from anywhere besides central London is one of my biggest anti-LHR bugbears. In many ways LGW is actually more accessible, with a proper 24/7 rail link…

    • Lady London says:

      Not quite 24/7. And often a pig on Sundays particularly Sunday nights.

      • George K says:

        I’d say while it’s down to one train an hour between 2am and 4am, that still qualifies as a 24/7 service.

        Although I will admit that if the line goes down for whatever reason, you’re stuck.

        • Lady London says:

          depends where you’re going

          • George K says:

            Sorry, I was referring to the central London to Gatwick service – either regular trains from London Bridge or Victoria (not the Gatwick Express), both stopping at East Croydon and then on to Gatwick. Although I understand the Brighton to Gatwick segment is equally popular…

  • L Allen says:

    “Not cheap” compared to what?

  • David S says:

    We have started using the Elizabeth line from T5 to Reading. Occasionally needs three trains in the evening as some terminate at Maidenhead. It beats planning to use the standard rail service which has never ending strike dates and overtime bans. Once you are away from T5 the Elizabeth trains are so frequent.
    Where we get stuck is working out if you can get a tube to T2/T3 and take advantage of more trains from T4.

    • Nick says:

      The tube is a pain as the walk at Heathrow Central is interminable. But if you’re ever at T5 and the next train to leave is a HEx, definitely jump on it and connect to a T4 Crossrail service, it’s always quicker than waiting for the next at T5 and will be the same platform at Central.

  • Abc says:

    Had the LHR T5 to Woking booked for Friday evening. It didnt turn up ! All of the links were running over an hour and a half late. I was informed they have new drivers and its chaos atm. Ended up getting the National Express home.
    A rail/air service needs to be reliable and this is definitely not currently.

  • Bagoly says:

    How far west do the tunnels extend?
    Only to the boundary of the foundations, or ender Stanwell Moor Rd, or under the M25?

    • Nick says:

      They don’t extend at all out of the airport. They were installed originally for the intended Staines link, but the rich Mortlake/Barnes/Richmond lobby put paid to that lest additional use of the level crossings delay their ‘essential’ 4×4 journeys. Conveniently the platforms were then available for the Western link to Langley, which nominally is still on the table but no work is currently planned. If it ever happens it’s likely to be a condition of a third runway.

  • Mark Bates says:

    There as a service many years ago from Watford to LHR. No idea when it was stopped but remember travelling on it around 20 years .
