Braving a drizzling rain and a long walk from the nearest metro station, the homeless were lining up outside the clinic of the Belgian charity Medecins Sans Frontieres. Viktor, a former inmate who now sleeps in Kazansky train station, demonstratively rolled up his trousers to show the bleeding ulcers on his leg that required bandaging; another man, diagnosed with dysentery, waited patiently for an ambulance; Olga, a young woman from Tver, said she came to get warm clothing and free pills for a disease she was too embarrassed to name. ""Nobody else is willing to take us in,"" said Olga. ""They are good people."" The doctors at Medecins Sans Frontieres offer free medical care each working day at this clinic in northern Moscow and in a converted camper-van outside Paveletsky train station. Before winter hits the city, they hope to have a larger bus that will allow them to help homeless people at other stations as well.
