Successfully linking West London to the south

The West London line is relatively short.
It links Clapham Junction in South London to Willesden Junction and it has always has an important cross London function as regards freight transport.
Originally it had a poor history as regards passenger transport.
Building started in 1836 and it opened as a passenger service in  1844s.
But was not a success and lasted six months!
Later there were other attempts to transport people on this route but it was not until around 2000 and the London Overground that things took off.
First the platforms at West Brompton were reinstated making another link to Earls Court and then in 2008 Shepherds Bush station was opened and the links to West London really took off.
The Central Line is across the road and the Circle and Hammersmith and City Lines are down the other end of the Bush!
The line seems to be packed throughout the day
