Trains are means of transportation that are used by people to avoid traffic congestion. However, train stations are also most frequently exposed to noise. This is due to the sound intensity of the operational activities in the location. Passengers and station officers are environmental components exposed to noise. In this study, the value of sound intensity level at the railway station of Medan city is measured using Sound Level Meter. This measurement was carried out for six days. The highest sound intensity level for the train departures is 96,67 dB and for the train arrival is 96,66 dB. Meanwhile, the lowest sound intensity level of train departures is 81,41 dB and the arrival of trains is 83,75 dB. It was found that the high level of sound intensity is sourced from the friction of the wheels with the rail surface, notification speakers and train horns. The results of this study can be used to find the most appropriate solution to reduce the noise level in the railway station area.
