About Northwick Park Station
This is a short multi with starting coordinates at Northwick Park Station which is on the Metropolitan line. It serves Northwick Park Hospital and the University of Westminster Harrow Campus.
The cache itself is a short walk away and you must gather the numbers from the clues below to gain the coordinates. All the details you need are in and around the station.
1. Walk through the alleyway to the Hospital/University. How many lamposts can you see in the circle just before the campus entrance (not silver ones) = A
2. On the walls in the alleyway you can see some black and white signs all starting with the letters MR. What is the single digit that appears in all signs greater than 0 = B
3. Retrace your steps back to the front of the station. How many cycle stands at the front do you see = C
4. What is the second digit of the bus on bus stop NN towards Harrow =D
Now solve this equation for the coordinates.
N51 34. (D)(B*2)+1)(C) W000 19. (D-D)(A+C)(C)
checksum for all numbers is 54
