Reduced Tube service on Bank Holiday Weekend?

it showed a pretty simple way to get there using the Circle Line straight to St. James Park.

From where?

Seems there are engineering works that day on the Circle Line anti clockwise from Edgware Rd.

If you are starting from Heathrow take the Elizabeth Line (forget all about the Heathrow Express) to Bond Street. Change to the Jubilee Line to Westminster. From there you can get the Circle Line clockwise to St James. Or walk. Or get a cab at Bond Street

There is no reason to go to Paddington. Forget the Hex, use the Elizabeth Line.

The alternative is take the Piccadilly Line to Hammersmith. Cross the platform and board a District Line train going to Upminster. Get off at St James.

Ohh ok, that might explain it then. Thanks for the info! It doesn't look like I'm able to use the Circle line from Westminster either. It shows taking the 11 bus or the 148. I don't mind buses, but I tend to get confused which side of the road I should be on for the direction I need to go.

This is due to engineering work. The line is closed for all 3 days this weekend through St James Park station, closed from Edgware Road and Hammersmith to Embankment.
So it is the Piccadilly Line from Heathrow to Green Park, change for either Victoria or Westminster, then self transfer the rest of the way - bus/taxi/walk.
Replacement buses don't run in Zone 1 as there are enough normal buses.

Thanks for the suggestions, that helps! :-)

I can’t see anywhere that the Circle Line clock wise is closed but anyway I would go the Hammersmith the District Line route with only one easy change

The engineering work calendar does not show that the track work is in one direction only. That would make zero sense in terms of health and safety. Full information will be on the update e mail tomorrow morning, but to me it is already Crystal clear, both directions closed.

Okay.
But it’s not crystal clear even, with an upper case C, when it says via Victoria.

I don't mind buses, but I tend to get confused which side of the road I should be on for the direction I need to go.

You may find this map useful. I assume you are transferring to bus at Westminster- so for either bus 11 or bus 148 you need to use Stop P at Westminster- just opposite Parliament and just before the main door of Westminster Abbey- https://content.tfl.gov.uk/bus-route-maps/westminster-a4-310723.pdf
The other way to do it is frequent National Express bus from Heathrow T2/T3 Central Bus station to Victoria then bus 11 in the other direction from straight outside the main door of Victoria Coach Station. The driver will put your luggage in the bus hold for the journey from Heathrow to Victoria.

Sorry to hijack this, but I just want to make sure I’m reading it right. The Piccadilly Line to Heathrow will not be available the weekend of May 25? Is that correct?

Thank you for the map link...that's definitely helpful!

KB, this is regarding the weekend of May 4th & 5th

BUT, @KB- As you ask- then looking forward, yes the Piccadilly is closed, in both directions, between Acton Town and Kings Cross on May 25 to 27.

Train Heathrow to Acton Town, then a half hour bus ride to Earl's Court (runs every 8 minutes) then the District Line; or a 20 minute bus ride to Hammersmith every 15 minutes for the Circle line/Hammersmith and City line clockwise via Paddington; or use the Elizabeth Line from Heathrow.

Jonna, with all the tube closures, I would go with the National Express coach option.

From the coach station in London, it's about a 20 minute walk to the St. James Park area or you could just grab a cab. It's a short ride.

Thank you, I will look into the coach option as well.

Additional note- due to local strike action by station staff Oxford Circus Station is liable to short notice closures between 2200 on Friday 3rd and 0600 on Sunday 5th.

Also Gloucester Road station is closed all weekend due to station engineering work
