Im sure that mayority of steam engines needs far less maintenance and are more dependable than DR1A. Only at fuel and oil consumption will that train better than steam trains. But about oil consumption im not sure: their gearboxes needs before every shift around 50-100 ltr hydraulic oil, what just drips to the nature through poor quality pipes and seals after 500km trip. Last times their maintenance was better and such oil waste ended.They use light 1000hp warboat's engines what are designed for war not for working tens thousands hours on civil use. That meant 3-4 engine failures per week for 14 trains.Their disc brake's quality are very poor, some wheels not brake, some brakes too hardly and stuck the wheels and make them beating. We had not any train with perfect wheels. Passenger rooms have not anything against noise, only foam plast packs between tin, you ride like in the trash container. Those beaten wheels make such noise over 80km/h that you must yell when you want to speak with other passengers. At winter are cars cold, snow flies in through windowframes.Only good feature was very simple electric circuits, even very stupid beginners locdriver helpers can cheat the sensors and replace fuses or make short connections and hold the aggregates running. So total failures where train stops and cant continue the trip, was surprisingly rarely.Ok i forgot train, what drips through front window seals on the controls and locdriver's timetables and other documents
