There are two daily trains from Istanbul’s Sirkeci station (one at 8:30AM in the morning, and the other at 3:50PM in the afternoon. Both arrives in Edirne about four hours later). Trains from Europe to Istanbul also call at the station.
The main station (signed as Edirne Gar on the station building) lies about 4 km east of downtown, close to the main avenue heading eastern suburbs of the city (which is also the main highway to Istanbul). However, all trains to Edirne drive onward west to Kapıkule (main borderpost on Bulgarian border) and call at Edirne Şehir station on the way, too, which is little more than a platform next to the rail tracks, lying less than a kilometre away from downtown to southwest, on the edge of the old quarter (Kaleiçi) and close to the banks of Tundzha.
