Vlaky.net has a nice report about the vehicles currently making their test rounds at the test tracks of Cerhenice (there was an open day at the 8th of May). IranRunner 1502 is there (No. 1503 is in Wegberg by the way), together with MRCE Dispolok ES 64 F4-111. Several Skoda units were spotted. New to us is a new ES 64 U4 locomotive: a red painted machine with number 183 702 (see picture). Production number of this machine is still unknown... did anyone check?For now we list it as Siemens 21323. - JP/NJ
