This post is dedicated to a photo album which used to belong to a British soldier named Albert Chalcroft who appears to have been posted in Landi Kotal in the Khyber Pass, (close to the Afghan border) in the late 1930s. As it often happens, the album was discovered by his descendants many years later (maybe c.2010) and was put up on the net.
This album is interesting in that it shows many aspects of life as a British soldier in the Khyber Pass area at that time. There are some pictures of trains on the Khyber Railway as well as a number of crashed light aircraft. Some pictures appear to show the road crossing between India and Afghanistan. However there are hardly any captions.
Many of these pictures have ended up in the results of Google searches for the Khyber Pass.
Landi Kotal was the terminus of the Khyber Railway which was opened in 1925. From 1926 to 1932 it ran a few miles further towards the border up to another station called Landi Khana, though this section was closed in 1932.
A collection of old timetables of the North Western Railway (which covered most of present-day Pakistan and a bit of present-day India) can be seen here:
The line up to Landi Khana can be seen in the folder of the 1930 timetable. Only a few routes are shown here.
The entire NWR timetable as of 1943 can also be seen in another folder, which is from the Indian Bradshaw of that period.
Note the bit about passport checks at Jamrud in the 1943 timetable. As I understood from older persons who had traveled there, tourists from other parts of India could travel up to Jamrud fort in the 1930s but not beyond without special permission. However, they could claim that they had seen the Khyber Pass.
And the milestone at the border refers to P = Peshawar, J = Jamrud (a cantonment at the lower end of the Khyber pass) and LKL = Landi Kotal (the main cantonment at the top of the pass).
The last few pictures show Mr Chalcroft and his wife in later years. He appears to have worked in the Customs and Excise department at Liverpool.
