It’s hard to imagine for the millions that live inside it, but entering into London’s subway/underground system can be a confusing mess for out-of-towners.

Knowing which line to take, or which numbered bus will whisk you to your destination isn’t information you magically garner overnight.

London Travel for WP7 hopes that it can provide more of a conclusive and quicker solution to navigating through the image-heavy TFL website, providing route-planning and interactive maps for all of the capital’s public transport systems.

For £1.99 you’d be forgiven for expecting a professionally presented experience, and this is exactly what the app offers, using the template swipe windows from WP7 to move through menus, and ensuring the backgrounds and icons remain large and clear throughout.

Navigation through the various functions is, therefore, a breeze, with statuses of the networks, travel planning, maps, and settings - for both internal and external apps like Twitter - all separated into their respective screens.

A neat feature for those that use Oyster cards (that’s essentially everyone who’s ever lived in London) is that you can link the app up with the online Oyster status service, allowing for quick reviews of your current balance without the mild embarrassment of getting a red light at the toll gates.

London transport doesn’t just piggy-back on the website’s functions, but adds a variety of features that take full advantage of the new platform as well.

One such function is the ‘nearest station’ option, that integrates into Bing maps to locate the nearest underground station from the current GPS position. Thankfully, it also provides a list of the nearest few stations as well, meaning that obscure lines such as the District line can be avoided.

One issue it does have, though, is in searching for stations. Should you mistype a station name, and that includes punctuation those that use ‘King’s Cross’ the program, London Travel won’t recognise the location. This can lead to empty responses to what should be routine route planning.

There’s also no option to plan out routes by bus, which, given that that particular mode of transport is the only one to run all through the night, somewhat lessens the usefulness of the app in certain situations.

With a slick interface, well laid-out menus, and extremely quick response time, London Transport is certainly a cut above the standard website planner. However the lack of buses holds it back from being the definitive travel planning product.
