<p> Lovers of retro posters must visit the <a href="http://www.ltmuseum.co.uk/" target="_blank">London Transport Museum</a>'s new exhibition Poster 150, which highlights the finest posters from the museum's archives, with 150 prints on display from 15 February. There will also be talks with authors, a quiz and a cocktail workshop. Plus an expert panel will discuss the stories behind the posters.</p>

<p> London's Brunel Museum commemorates the Thames Tunnel as the birthplace of the Tube system. The tunnel is also celebrating its birthday this year as it turns 170. Built by Marc Brunel and his son Isambard Kingdom Brunel, it is the oldest tunnel in London. It was designed to carry cargo from one side of the river to the other, but this proved too expensive, so the tunnel opened as a tourist attraction in 1843. In 1869 the first passenger trains ran through it and it was later used as part of the East London Underground line before it became part of the London Overground. &pound;3 for adults; free for under-16s.</p>

<p> From 8 to 12 April and 28 October to 1 November, the <a href="http://www.ltmuseum.co.uk/" target="_blank">London Transport Museum</a> is inviting you to go behind the scenes at its depot in Acton, with a whole host of events, including the chance to learn more about the restoration of the Met Railway Carriage No 353 with the Ffestiniog Railway and Met Loco No. 1, which will be on display, as well as photography and creative writing themed days.</p>

<p> If you can't get enough of Britain's railway history and want to explore the London Underground, Kent and Essex Railway, London's preserved railways and more, you'll want to book <a href="http://www.ffestiniogtravel.com/index.php/uk/connoisseur-rail-tours/london-and-south-east" target="_blank">Ffestiniog Travel</a>'s ten-day Behind the Scenes in London &amp; the South East break, which visits the region&rsquo;s oldest and newest railways, dropping in on depots and uncovering hidden secrets of the capital&rsquo;s transport system. Departing 25 April, the holiday costs &pound;1,360 per person (based on two sharing) and includes standard class rail journeys, a seven-day Oyster Travelcard, nine nights&rsquo; B&amp;B, excursions, some meals and an experienced tour leader.</p>

<p> It's not just London that has a brilliant underground history. If you're looking for something further afield, visit <a href="http://www.chislehurst-caves.co.uk/" target="_blank">Chislehurst Caves</a> in Kent, a labyrinth of man-made tunnels forming a maze and stretching over six hectares, 30 metres below the woodlands above. Originally dug from chalk used in lime burning and brick-making for London's buildings, the caves became an air raid shelter in World War 2, and today you can still see a hospital and chapel that remain in the site. &pound;5 for adults; &pound;3 for children.</p>

<p> Head for Manchester to attend steam school and learn how to ride and operate the world's first passenger train at the <a href="http://www.mosi.org.uk/" target="_blank">Museum of Science and Industry</a>. Housed in the original buildings of Manchester's Liverpool Road station, which dates back to 1830 and was once used to transport goods between the port of Liverpool and the industrial power house of Manchester, it is now the oldest surviving passenger railway station in the world. The 4.5-hour Steam School experience takes place monthly and costs &pound;250.</p>

<p> Ever wanted to see inside a sewer? In Brighton, the <a href="http://sewertours.southernwater.co.uk/" target="_blank">sewer tours</a> give visitors a whole new perspective on the vibrant city. On the tour you'll discover clean spring water bubbling beneath your feet from a freshwater river that runs under the city, learn fascinating facts about landmarks above ground and find out why Brighton's beaches are cobbled not sandy. &pound;12 per adult; &pound;6 per child.</p>

<p> Ok, so it sounds like an obvious one, but how about using your Oyster card and taking the Tube to somewhere new and exciting you haven't visited before? We're not encouraging you to join the crowds at rush hour but when it's quieter you can discover plenty on the London Underground network. Be sure to take in the stations themselves, where there's art and interesting finds you won't want to miss. For example, at Gloucester Road there is a fabulous art installation on a disused platform, Southwark Station is architecturally stunning with its dazzling blue glass wall and look out for the blue police box outside Earl's Court (one for Doctor Who fans!).
