@Blaamand, you might find this norwegian one interesting then
i apologize for taking the subject hostage to show something not in thread with the orginal post
add a danish one with 946 - I do not know the name of the town
Just a beautiful example of the danish -> norway mail system.
and now back to Sweden. Naturally there have been quite alot of post passing the narrow strait between Sweden and Denmark.
as earlier mentioned, a letter posted on the docks or aboard a ship would typically be cancelled with the recieving country's postmarks.
these "strips" didn't get a cancel until reaching the destination train.
PKPX No 2. Upp: No. 2 refers to lines to and from Malmö, i'm assuming the Upp means it's going from Malmö and Upp"wards" maybe to Falköbing or Nässjo which both are quite a bit north of Malmö
there is listed an PKXP No 2. Ned Ned means down, so I may be incorrect but it sounds logical to me.
many letters would aside from a postmark on the stamps have this line cancellation stating where they originated from.
Text reads Frän Danmark meaning, From Denmark
the more a read about this, the more fascinating I find this, maybe I should start collecting the railway stuff :)
