Whether it is wild orchids, reptiles or giant eels, all have been given new homes thanks to Network Rail following the start of its works on behalf of Crossrail in the Stockley Junction area in West London.
Before work began on the Stockley Interchange in late March, which will allow Crossrail services to operate to and from Heathrow Airport, ecological surveys had identified locations of protected and invasive fauna. An initial relocation of reptiles and amphibians took place in advance of the construction works to avoid delays to the project.
Then, as construction began, the rescue operation really kicked into gear as Network Rail, together with contractor Carillion, aquatic consultants and the Environment Agency, cleared and lowered nearby Anderson Pond. It was then electro-fished, a technique which temporarily stuns fish, allowing them to be surveyed and returned to the water unharmed.
A total of 599 fish were safely caught and relocated to a new home. Species found included tench, roach, rudd and bream, all of which were held in an aerated tank to recover before their relocation to Pondwood Fisheries near Maidenhead.
The real catch of the day, however, was a European eel, which is a critically endangered species. It weighed an exceptional 5lbs and came in at 3ft long. It takes about 10 years for an eel to put on a pound so this one could be 50 years old.
Meanwhile, 30 wild orchids were saved and relocated to similar habitat at Maple Lodge Nature Reserve.
Courtesy of the Maple Lodge Conservation Society, Network Rail moved the plants to their new home in Hertfordshire where they can be protected but also enjoyed by the public.
All this good work was preceded by relocating 46 protected slow-worms, 593 newts and five frogs from the Stockley area to new homes in August last year, following consultation with the London Borough of Hillingdon.
Michaela Payne, environment specialist at Network Rail, said: ^Our Network Rail Crossrail Programme has set a target of no net loss for biodiversity. To this end the work we have done at Stockley will ensure that the biodiversity in the local area is protected and enhanced for the community. Delivering these works will have a lasting legacy of both improvements to the railway infrastructure and enhancements to the natural environment.
^This underlines the commitment that the project team has made to the delivery of sustainable development.^
About Crossrail
Crossrail will run 73 miles from Maidenhead and Heathrow in the west, through new twin-bore 13-mile tunnels under central London to Shenfield and Abbey Wood in the east. It will bring an additional 1.5m people within 45 minutes commuting distance of London's key business districts. When it opens from 2018, Crossrail will provide new transport links with the Tube, Thameslink, National Rail,
DLR▸ and London Overground.
Network Rail delivering Crossrail
Network Rail is a key partner in Crossrail and is making significant investment in upgrading the network around the Capital to deliver it. This complements Network Rail^s other work to increase capacity and improve performance across Britain.
Network Rail is responsible for the design, development and delivery of the parts of Crossrail that are on the existing network. Its work will integrate Crossrail with the national rail network, delivering faster, more frequent trains into central London from the east and west. The work includes upgrading 43 miles of track, redeveloping 27 stations, and renewing more than 20 bridges.
Network Rail will do all of this on an active operational railway, delivering vital upgrade works whilst minimising disruption to train services.

Stockley Interchange
The Stockley interchange is a crucial part of the Crossrail network that will allow Crossrail trains to join the branch to Heathrow without delaying - or being delayed by - fast trains to the west, thus increasing capacity and reliability on the extremely busy Great Western main line. The current junction at Stockley allows trains to leave the main line and continue to Heathrow Airport. Network Rail, on behalf of Crossrail Limited, will build a new single track viaduct for all trains from Heathrow towards London. Works are due to complete in 2017. Existing train services to Heathrow will continue to run throughout.
