Subway systems, light rail transit and freight trains can send loud train noise into neighborhoods. Organizations such as the World Health Organization [1] and the U.S. Environmental Protection Agency have set guidelines for noise level decibel limits for rapid transit. Noise levels can be reduced by installing noise barriers next to the track. [2]
Railroad caused vibration is preempted by federal law (CFR 201). Chicago, IL (Section 11-4-2910) uses the perception threshold method. Dallas, TX requires measurement of low frequency vibration. Maryland uses the definition of noise to include sound and vibration at sub-audible frequencies.

Electric trains have a higher power-to-weight ratio (no onboard fuel tanks), resulting in fewer locomotives, faster acceleration, higher practical limit of power, higher limit of speed, less noise pollution (quieter operation). The faster acceleration clears lines more quickly to run more trains on the track in urban rail uses.
