electronics and regenerative braking. Up to the point of their introduction, no other KTM motive power used these modern train control systems. Designated by KTM as "Class 8x"s, the EMUs wear a yellow, blue and grey livery, a departure from the predominantly grey livery that KTM adopted on other locomotives and passenger coaches at the time. A handful of EMUs include full advertisements on the sides of their cars. The original Komuter fleet consisted of the following models: The Class 8x suffered from more mechanical problems as they aged, especially the Class 81 and Class 82, which had poor reliability. The manufacturers of both classes had gone bankrupt since the trains were built, hence spare parts became unavailable. On paper, the number of serviceable units in 2010 stood at 53 out of the original 62, although there are reports of far fewer trains. Ultimately, four Class 81 sets were refurbished, albeit with new motors from Hyundai instead of Jenbacher. All Class 82s were taken out of service. In 2012, six-car Class 92s were introduced, replacing most of the Class 8x in the central sector. A handful of them remain, usually on the Skypark Link or Sentul-Batu Caves shuttle, but many have been reallocated to the northern sector. Ridership Ridership statistics published by the Ministry of Transport are for all KTM Komuter services. No separate statistics for the individual lines or operational regions are published. Statistics before 1999 are also not available. Incidents and accidents On the evening of 3 March 2004, a Seremban-bound KTM Komuter train in the Seremban Line collided with the rear of another Komuter train facing the same direction, which had been waiting at a signal between Tiroi station and Seremban station for five minutes. Forty were injured, but no deaths were reported. The accident was ascribed to the faulty signal light (struck by lightning) that stopped the earlier train, though the driver of the rear-ending train is reported to have run a red light into the section occupied by the rear-ended train. The resulting crash disrupted KTM Komuter services along the line for a day. This is so far the worst accident involving the KTM Komuter service. On 2 March 2007, a crane fell onto a KTM Komuter train track near the Sentul-Port Klang Route's Shah Alam Komuter station, stranding about 10,000 passengers and cancelling 40 trips. Alternative transport services were provided. On 25 May 2007,
