Since that time, in accordance with a UIC directive, locomotives and crews increasingly often travel over routes of foreign railways.

Poland is not a country with a large number of tunnels, neither road nor railway, as the largest part of the country lies on flat terrain. Of the 34 standard-gauge tunnels found inside Polish borders after 1945, ? three are located on industrial railways, ? as a result of a border correction between Poland and then-Czechoslovakia in 1958, one tunnel was transferred to then-CSD (recently CD), ? one, lying aside the Rzeszow-Jaslo line, was not used for trains after World War II, ? the remaining 29 tunnels, with a combined length of 17,021m lie on lines belonging to today's PKP Polskich Linii Kolejach S.A. (Polish Railway Lines - the infrastructure operator), with as many as 18 being located in Lower Silesia. Of the two narrow-gauge tunnels, one is located near Jawornik Polski, and via the second runs the line connecting the excavation pits of the Opole cement factory.

Steam locomotives of the Prussian KPEV T93 series, later BR 91.3-18 DRG (TKi3 PKP) were built in the years 1901-1914 for use in shunting service and on light passenger-freight duties on secondary lines. At least 2257 examples of these locomotives were built in 12 factories. On the pre-war PKP roster, the TKi3 tank engines made up the most numerous series - 320 of them were used, amongst these 10 on the territory of the Free City of Gdansk. Post-war, 247 returned to work on the PKP and industry, of which 246 received postwar TKi3 numbers. These locomotives were in used until the middle of the 1960s. The last, TKi3-170, was removed from the roster of MD Kamieniec Ząbkowicki on 21.01.1970. A number made their way into industrial use, where they served until the end of the 1970s.  

Anyone may participate in a FREMO (Friendship of European Railway Modellers) meeting. No one is required to have their own modules or rolling stock. At a FREMO meeting, anyone may take part in "role distribution" and select for oneself a position, be it as a stationmaster, locomotive driver or something else. Of course, one may also take on the position of "observer". The train layout becomes only a setting, a beautiful background for fun, in such a form as...well, really only something else counts. The idea of a FREMO-meeting is shared enjoyment in modeling railway operations, running a passenger timetable, and purposeful freight operations, and although some grumbles might be heard, the FREMO-caravans goes on... for 30 years already.
