This cache is at the former Morningside Road Station. It is the
sister cache to Craiglockhart
Station and Colinton
Station, and so now it forms a series! You may have guessed the
theme by now... 
.
The cache is not at the above coordinates, but is very close
by. The coords do, however, give a nice view of the old station
from the old footbridge. It was opened by the Edinburgh Suburban
and Southside Junction Railway (ESSJR) on 1 December 1884 as
Morningside Station. On 1 March 1885 the ESSJR was incorporated
into the North British Railway, and the station was renamed
Morningside Road in October 1886.
Morningside Road station closed in 1962, when passenger rail
services were withdrawn from the Edinburgh Suburban line by the
famous Dr Beeching - the man in charge of cutting over 4000 miles
of track in Britain. However, the line is still used for rail
freight use, and occasionally diverted passenger trains also pass
through Morningside.
The station is located by Morningside Road, where the road
bridge crosses the suburban line, and it used to be accessed via a
gate on the west side of the road, opposite the Morningside
Clock.
Today the station is derelict and the entrance to the station is
now occupied by a branch of the Halifax Bank of Scotland. The
island platform has been removed although the track formation is
still split. ScotRail retains an advertising hoarding on the bridge
next to the clock, where they display posters advertising passenger
rail services (see if you can spot it).
To find the cache, you will need to solve the following puzzle.
The cache is the same size as Craiglockhart Station (so it will be
able to house small TBs/GCs), but it is hidden in a very different
way; one of its features this time is it's magnetic. Once again,
there is a bit of cammo as the final location is rather busy, so
just be careful! However, if your stealth is up to scratch, then
you shouldn't have too many problems retrieving the cache 
.
The cache is at:
N 55° AB.CD
W 003° E.FGH where:
A = mega + deci
B = kilo + hecto
C = tera - mega - deca
D = yotta + kilo
E = tera
F = pico + exa
G = centi - micro
H = nano + peta - milli
You can check your answer to this puzzle on

Please do NOT give any hints or clues in your log as to
where the cache is so everyone can enjoy the puzzle. And remember,
the container is the same as the one used in Craiglockhart Station,
so remember to push on the lid and then turn . Hope you enjoy the cache!
Update May 2010: There is now another cache to add to the
