London Tube - time to account for planned engineering works?

Hi.

I have an appointment in London next week, and when I check the Transport for London Website, it says that engineering work is planned on my possible tube routes.

How much extra time should I add to my journey account for this?

I have to reserve a pricy rail ticket from York to get to London so I need to get my scheduling right.

The details are that I need to get from Kings Cross to either Regents Park, Baker Street or Great Portland Street.

Hi,

King's Cross to either Baker Street or Great Portland Street only takes about 5 to 10 minutes, so if it were me I'd budget 20 just to be really safe and take into account the walk from the National Rail part of the station to the Tube part of the station.

Just in case you haven't seen it, there's a journey planner that's pretty good:

good luck,

Thanks Carl.

I was using the tfl.gov.uk Journey Planner, but your link doesn't work.

You're on the right Journey Planner.  I fixed the link so hopefully it works now.
