GZ for this cache is reached via a tarmac footpath. During morning and afternoon peak times it is a busy thoroughfare so probably best not attempted at these times - if you do, please be very stealthy. Please also rehide exactly as found so as not to be visible by passing muggles. Happy hunting!
The reason for placing this cache here will become apparent if you continue and walk up onto the footbridge. Here you can look down the line towards Poole station and will quite likely to see trains stored in the sidings on the left. Looking the other way, towards Fleetsbridge, you will see the track curves round before then heading on and crossing Holes Bay to its final destination, Weymouth!
This is a really good place to come and photograph steam trains and other special chartered trains. I have seen and photographed many such trains here.
