According to the present staggers and the data tested under train vibration by the inspection cars foroverhead contact line equipment inYingtan-Xiamen railway, and the current commonly-used compensation algorithmfor staggers, a newalgorithmwhich is based on the BP neural network is developed for compensating the staggers of overhead contact network under train vibration. It provides a basis for power supply sections to conduct static inspections by using dynamic inspection data obtained by inspection cars. Experimental results show that: compared with the manually measured data, the compensated resultswith a tolerance less than
30 mm amount to 80% in the total line.
