4) resistive braking controls by DB catalyst, and braking power can not accurately control, and arcing during the load disjunction of D.C. contactor band, and fault rate is high；
5) door safety interlocking adopts mechanical switch interlocking, and opposite house installation accuracy requires height, easily reports by mistake；
6) there is no high pressure warning lamp, it is impossible to intermediate circuit voltage is judged intuitively, during maintenance, have security risk.
Additionally the shortcoming of EMD internal combustion car converter device has:
1) commutator separates with inverter, and distant, and integrated level is low, the converter device that dependent is placed；
2) converter device main circuit adopts built on stilts topological structure, if single inverter lost efficacy, then and the power of car load loss half；
3) there is no a safety interlock device, there is potential safety hazard.
4) there is no high pressure warning lamp, it is impossible to intermediate circuit voltage is judged intuitively, during maintenance, have security risk.
5) air-cooled radiating mode is adopted, when outside bad environments, it is necessary to spend a lot of cost cleaning radiator.
