 Cars from Halle are used today in Kaliningrad, Iaşi, Belgrade (one car, garage number 1004), Sofia; Leipzig and Dresden vehicles are used in Pyongyang (North Korea) and Rostov-on-Don (Russia).Despite still being in working order, the T4Ds were withdrawn from regular service in Dresden mostly due to accessibility concerns, as low floor vehicles are now mandated for all new purchases.The T4D still sees service on lines to and from Dresden Technical University and during the Christmas market in order to deliver more frequency.
