London Transport Museum

I went a few years ago. It was a good experience and I recall that we spent 2-3 hours there.

A small museum, a lot smaller than the National Railway Museum in York.
I would agree 2 hours, 3 tops. It is in Covent Garden, so lots of other things to see in the area.
I would schedule it for a rainy day, or if you have kids with you.

Thank you both, your reponses were really helpful. I saw it, when I was in London this year but walked around Convent Garden and Neal's Yard but had no time to go in. Now I will make the time!

I haven't been for many years but I do hear that they have really updated and improved it - and it was pretty good then. My memory is that it isn't free or even cheap to visit, but I think that they participate in the railway 2 for 1 scheme.

They also have a large usually not open to the public collection in Acton, West London, which is open on certain days. The website would say if one of those days is during your visit.

Although you said you were looking for something different, there is quite a lot of art content in the museum, the most obvious being the poster collection.

Marco --- That sounds great. It is on my list to visit and see Covent Gardens again.

Also something different is the spectacular James Bond in Motion exhibit at the film museum right around the corner from the Transport Museum:

If you are a Bond fan is a must see!

The London Transportation Museum is terrific. Not on the scale of the RR Museum in York, but focused on London's historical buses, the Tube, etc. We have been twice as I live with a transportation junky (though I like it too). You might look into the London Underground tour with Insider London as a companion activity.

Museum of London is excellent, National Gallery (took me four trips to London to work it in) is now one of my favorites in all of Europe.

Yes look for the Poster Girls exhibit, all designed by women artists. I’m looking forward to seeing it next month. And also if you’re not already aware, your admission ticket is good for return visits within a year.

A great stop. I love the museum shop as they sell posters/lithographs of some the great rail advertising campaigns dating back 100 years. Enjoy!

I enjoyed it very much. It's not really huge--it's manageable in a couple or three hours.

However...there were a lot of children there. I was there during the school break, however. But if you don't mind kids running back and forth and around, you will be fine!

Thanks everyone for your responses and advice. It really helps!
