While "Bank Quay" and "Central" still exist today, at one time
Warrington had a third town centre station - "Arpley", which was
just west of Stage 1. Opened in 1854 as part of the St. Helens
Railway and Warrington & Stockport Railway. It was finally
closed to passengers in 1958, and demolished in 1960. The railway
line remained in use until 1985, when it was closed beyond
Latchford, although this section is still in use as sidings, for
coal trains heading to fiddlers ferry power station.

Subterranea Britannica Site.
You may wish to cross the Mersey by way of one of the two
underused footbridges near to Stage 1, but please don't jump up and
down too much - those metal plates don't look too sturdy 
- Stage 1 contains the co-ordinates
for Stage 2, which is a small clip-lock style plastic box, with
room for a (small) trackable. Access to stage 2 may be restricted
at night. Please rehide both stages carefully.
