Blackheath railway station is Grade II-listed and is in the south-centre of Blackheath, a village in southeast London. It is 8 miles 52 chains (13.9 km) measured from London Victoria. Much of the original station, dating back at track level to and opened on 30 July 1849 but at ticket office level to 1879, remains.
It was built using London bricks to a design by George Smith.
Blackheath station has two platforms which are partially covered with a weather canopy. Glass and metal waiting shelters were erected on the London ends of both platforms in April 2018.
There is a disused platform (bay platform) facing towards London, used in earlier days by commuter trains terminating here, then later for the arrival of Circus animals .
The rails have gone but the track bed remains obvious, with new power and signalling equipment using the space so is obstructed.
Current off peak services are 4 trains per hour to/from Charing Cross and Gravesend. 2 trains per hour to/from Cannon St and Barneshurst. 2 trains per hour to/from Victoria and Dartford.
If you solved this with the numbers from the Black and White Heritage Sign which went missing in June 2021 your numbers should still take you to GZ however they can be double checked.
Now for the cache.
At the first stage you will see a sign which will reveal numbers BEX NPQ Rm STch
Use these in the order found to reveal the final by using the following simple calculation
N 51° (N-Q)R.(P+Q)(R-N)(Q*Q) E 000° TS.(R-P)R(R-Q)
The cache is of course a short walk away.
Happy hunting for this camouflaged pot
