In this paper, interior noise that is brought into inside of coach when it passes by straight line track, railway turnout section, curved track, and rail lubricator section with test coach was measured in accordance of track characteristic of urban railway vehicle. It was evaluated with 60km/h of constant speed in the motorized trailer, no.3 car T1 motorized trailer of urban railway vehicle. Interior noise characteristic value is higher in order of curve, rail lubricator, railway turnout, and straight track as a result of the test. The highest characteristic value is 86.7dB in the curved track. And, the lowest characteristics value is 75.5dB(A) in the straight track. For accurate result comparison, it is transformed into sound pressure distribution by time domain, sound pressure level by time domain, sound pressure level for frequency domain and completed analysis.
