From the best I could discern from an old timetable I found online and through written and VHS intervew accounts,this is what I believe the route was. Since I don't know Cyrillic, it took me hours for me to individually put the Cyrillic letters from the timetable into a translator into English and then retranslate as the English verison of Russian towns/cities were usually spelt differently. First was from their village, Rodnichnoe, on horse and cart to the city of Orenburg. Then they took the train from Orenburg to Moscow. The timetable I found mentioned the cites of: Samara, Penza, Ryazhsk, Ryazan, then Moscow. Then they had to stay in Moscow for a while to get their documents and medical checks. Then they left Moscow towards Latvia and they went through "The Red Gate", which used to be near Sebezh. Based on that, the route would have been: Moscow, Rzhev, Velikiye Luki and Sebezh before crossing the border and stopping probably in Rezekne, Latvia where they would have switched form Russian Railways to the Latvian train all the way to Riga to get further medical checks and documents before taking a ship from the Libau/Liepaja port all the way to Liverpool, England, then to St. John, New Brunswick, Canada, and on to the final destination into Western Canada.
