Maximise your Avios, air miles and hotel points

Did you know Thameslink always declassifies the rear First Class carriage?

As anyone who read my University Arms hotel review will know, I was in Cambridge recently to ferry my son to a summer school.

Whilst there are a number of rail options to Cambridge, we ended up on a Thameslink service from London St Pancras.

This reminded me of a little known bit of London rail trivia. The rear First Class carriage on Thameslink is always declassified.

By ‘declassified’, Thameslink means ‘is treated as Standard Class’.

This means that you can sit in the REAR First Class carriage on any Thameslink train with a Standard Class ticket.

It is confirmed on the Thameslink website here – click and expand the question ‘Is First Class available on all Thameslink trains?’.

You will NOT see any signage on the train to confirm this although it is often mentioned on the scrolling digital display inside.

As with all of the London suburban rail networks, First Class isn’t substantially better than Standard Class. You do, however, get a table and more spacious seating. I believe these are also the only carriages with power sockets. First Class is also quieter, even in the declassified coach, because most people don’t know that anyone can sit there.

(We had an American couple sat opposite us who, based on their conversation, had clearly paid for a First Class ticket. We hadn’t.)

The declassfied coach is identical to the ‘real’ First Class carriage at the front of the train. This is obvious when you think about it, because on the return journey the carriage that was at the front is now at the back!

ALL First Class is declassified on some routes

This information is REALLY hidden away, but some Thameslink routes declassify all of their First Class seats, at the front and the back of the train, because First Class tickets are not sold for those services.

There is a 2019 map showing these routes in this X post.

Assuming nothing has changed, both First Class carriages are declassified if your train terminates at:

  • Luton
  • St Albans
  • West Hampstead Thameslink
  • Kentish Town
  • Wimbledon
  • Sutton
  • Orpington
  • Rainham
  • Sevenoaks

  • Simon says:

    First class is also declassified on all trains on the Waterloo-Reading line via Clapham and Staines, including the Windsor and Eton Riverside branch. Not all of the trains on this line have First, but anyone can sit in the compartment for those that do.

  • Andrew Halket says:

    Surely when leaving London it’s the FRONT 1st class that’s declassified.

    • Andrew Halket says:

      Oh but Thameslink trains run THROUGH St Pancras… was confusing with trains from KINGS x

    • Rob says:

      No. Always the rear carriage, which means that the declassified carriage switches depending on the direction of travel (there is a First carriage at the very front and very back).

  • SteveCroydon says:

    Pedant Alert! That picture is of an ancient ThamesLink class 319, probably now razor blades or operating up t’north somewhere near Liverpool. They have been gone for years, having been replaced by class 700. The 319s had more comfortable seats than the ironing board seating on 700s, however 700s have much better suspension. Travelling on 319s was like being on a waterbed!

    • Andrew says:

      Yup – no opening windows on the trains now.

      I remember the old trains on the Cambridge line where you had to open the window to open the doors from the outside

  • Andy S says:

    Also the peak time only Sevenoaks to Welwyn Garden City Thameslink trains are all declassified.

  • Alex says:

    First heard about this on Geoff Marshall’s YouTube channel, been on there ever since 🙂

    Slight correction:
    “You will NOT see any signage on the train to confirm this although it is often mentioned on the scrolling digital display inside.”

    You do see a signage – through the digital display while you are inside the rear first class carriage. Here’s an example:

      …which is exactly what the article says:

      “it is often mentioned on the scrolling digital display inside [the carriage]”

      • Rob says:

        I added that in as a result of comments!

        • Barrel for Scraping says:

          Although it’s not scrolling, it’s an information screen and the declassified information is one of the messages in the rotation. Others include carriage occupancy (so if the train is busy you can find a quieter spot), tube status, toilet status, etc

  • teddyboy says:

    The announcement on the platform always says “First Class is at the front of the train”, and the display screen in the rear ‘first class’ section periodically displays a warning (with a big red exclamation mark) saying “This area may be used by customers holding standard class tickets”.

  • Thomas Atkins says:

    If not already mentioned, same declassified 1st class carriage (I’d suggest rear one only) also applies to trains terminating at Cambridge and Peterborough. Thank me later 😁

  • Pb says:

    Do you get a refund if you had bought a first class ticket or do they simply not sell them on declassified services ?

    • Rob says:

      On the part-declassified service you can sit in the front carriage with an F ticket. This is not declassified.

      On a fully declassified service, in theory F shouldn’t be sold.

    • John says:

      If it’s declassified on the day (which can happen due to crowding) you can claim a refund of the difference through customer service, and then separately claim delay repay if applicable.
