Amanullah left Warsaw1 by train on the morning of Wednesday 2 May 1928.
Białystok station was decorated with Polish and Afghan flags. The visit of an exotic guest attracted people to the station, but the police only allowed people with special passes on to the platform. Representatives of administrative and military authorities, social organizations and the press started arriving at the station at noon.
King Amanullah at Białystok
The train arrived on time 12.50, as a military band played the Afghan national anthem. Amanullah appeared at the window in civilian clothes, when General Sosnkowski and Colonel Wieniawa-Długoszewski alighted onto the platform. Local dignatiories boarded, and Deputy Voivode Skrzyński entered the coach and welcomed the king in French; he answered in his own language, expressing thanks for their best wishes and admiration for the Polish army.2
The train then continuted to the Polish border town of Stołpce (now Stowbtsy in Belarus), where Amanullah changed to a Soviet train and was due to enter the Soviet Union at 20.00. The Times reported that the wooden arch spanning the tracks a yard inside the Soviet border had been specially decorated,3 as seen in the photograph.
There were further speeches, guards of honour and anthems at Negoreloye and Minsk.

Just south of Termez, at Heratan, on the Amu Darya river, diplomats understand that a reinforced steel bridge is being constructed. The aim, it would seem, is to improve the roads and garrison facilities right from the Soviet border to Kabul
