The Montreal, Maine &amp; Atlantic Railway, the corporate successor to BAR, owned #42, which was renumbered back to its original number, 502, when it was repainted into the original gray and yellow scheme. After the Lac-Mégantic rail disaster and the subsequent bankruptcy and liquidation of the railway, this locomotive was purchased, along with most of the rest of the former railway's assets, by the Fortress Investment Group and formed into the Central Maine and Quebec Railway.
