The West Coast Main Line runs from London Euston Station to Glasgow Central via Birmingham, Liverpool and Manchester. It is the busiest mixed use railway in Europe and is the backbone of Britain's Railways.
This cache is located on the a sign near the low bridge under the railway. The cache is a micro container and is camoflagued well. Parking is just past the sign. If you understand the clue, you will find it easily. The road is very quiet and you might only see a farmer and some cyclists. The Road is not suitable for vehicles over 2.3M wide and 2.3M tall due to the narrow bridge. Trains pass by every couple of minutes and some will hoot the horn if you wave. Bring your own pen and possibly tweezers.
Congratulations to 6669 for the FTF! (Again!)
