Emaxim --Thanks .....I believe anyone looking for these Railway cancellations would be better off looking for them with the Cyprus collectors who specialize in Rural Postal Agencies .
These Rural Postal cancels{R.P.C.} came some 20 years before the railroad cancels . My guess is these R.P.C. were more common having been canceled at the receiving Post Office in the large villages and towns ,so there was no reason for the railroads to cancel the mails with a railway cancel. Here below is the cancels type that really was more common if the railroad carried the mail .

I believe those stations on the rail line were already established as Rural Post offices or had that cancel device many years earlier than the Rail cancel was started .
