OPTICAL MEANS OF MEASURING THE VISIBILITY OF LOCOMOTIVE EXHAUST

This paper describes how optical smokemeters can be used to accurately measure and record the visibility of locomotive engine exhaust. Data derived from these measurements can be utilized in helping to assess a level of engine performance for new locomotives being delivered from builders and for locomotives following major repairs. The data are also useful as documentary evidence to mitigate cases where a locomotive has been cited by regulatory authorities for alleged excessive smoking. Smokemeters are an important and effective means for monitoring visible locomotive exhaust emissions and enabling railroads to safisfy air pollution requirements.
