Prototype information

ER 20 in "alex" Railroad Operations. The diesel-electric powered ER 20 is a member of the technically very modern EuroRunner locomotive family. Siemens Dispolok GmbH has been leasing out these units from the large EuroRunner production run since 2002. These locomotives are suitable for freight service as well as for passenger train service. These units put out 2,000 kilowatts / 2,681 horsepower and are currently authorized to run in Germany and Austria. The latest diesel motor technology and a new type of noise dampening make the ER 20 one of the quietest diesel locomotives with the lowest level of exhaust gases in Europe. If necessary, these locomotives can be adapted in appearance and technically on request to the various requirements of customers for use on national or European main or branch lines. The consortium from the "Provincial Railroad" (brand name for the Regental Railroad AG/Regental Railroad Operations GmbH) and EuroThurbo GmbH (German subsidiary of the Swiss firm Thurbo AG) is one of Siemens Dispolok"s lease locomotive customers. These two partners jointly run the Allgäu Express from Munich to Oberstdorf, which has its logo "alex" on the Siemens Dispo locomotives. These locomotives with their contrasting yellow-white-aluminum paint scheme are a real eye catcher in railroad operations in the alpine foothills.
