And now to walk the entire length of the original Bakerloo line, above ground, to see what's there. It's only three miles from Baker Street to Lambeth North, but there's absolutely tons to see.
Today I'm tracing the tracks from Baker Street to Regent's Park station. Here's an old map showing the geographical route (northeast-ish), which is absolutely nothing like the fantasy route (southeast) depicted on the official London Underground tube map. Whatever today's map may say, the Bakerloo line definitely runs to the north of the Circle line between Edgware Road and Regent's Park, and not to the south.
[I would at this point show you the relevant tiny snippet of the current London Underground tube map, but it's probably best not to for scary legal reasons. And if you're a fan of strange and wonderful tube maps (like the anagram one, the sweary one and the upsidedown one) then you might want to head over to Geoff's map archive and download as many as you can before TfL's humourless solicitors move in on Monday and extinguish the lot].
The first eastward building you meet on leaving Baker Street station is one of the most famous in London - the Planetarium. Its green copper roof is instantly recognisable, as is the small ringed planet perched right on the top of the dome [photo]. As a child I remember reclining on the comfy seats inside the Planetarium and being totally overawed by the astronomical lightshow projected onto the roof above me. I quite fancied going back for another look this year, except that the show has now been dumbed down to a mere ten minutes and entrance is only available as part of a combined ticket with Madame Tussaud's nextdoor. Sorry, but there's no way I'm forking out £22 (yes, £22!) to gawp at a few waxwork celebrities, even if some are supposedly interactive and reveal a bit of greasy flesh. Tragically the owners have decided that the only stars which attract tourists nowadays are of the two-legged kind, so in June the Planetarium in its current form will be closed and transformed into the Auditorium - a new audio-visual show which promises to "get into the heart of celebrity". Sounds absolutely ghastly, but I'm sure the vacuous crowds of tourists who throng the Marylebone Road will lap it up.
From here the underground Bakerloo line skirts the southern edge of Regent's Park. This is one of the largest open spaces in central London, transformed from Tudor hunting lands into elegant parkland by John Nash. He's also responsible for the imposing terraced villas which line the edges of the park [photo], now home to the aspirationally exclusive. I passed several moneyed old couples out taking a stroll through the park, the men gnarled and grimacing, ostentatiously parading their fur-coated wives and pampered dogs. Younger visitors cycled, or jogged, or even scootered, while out on Marylebone Green a semi-serious soccer kickabout was underway. The scenic central lake [photo] is actually part of the old River Tyburn, here visible for the one and only time before plunging beneath the city of Westminster on its way to the Thames. At the moment a carpet of daffodils is pushing bravely through the winter mud, but it won't be long before this lovely park truly springs to life.
