<i>Sectional Map of New York, New Haven and Hartford Railroad Eastern District, Cape Cod.</i> 
<br>This map appears to be a re-branded version of the 1888 Old Colony Railroad (OCRR) map (linked below), with the only addition being a road between Middleboro and Plymouth.  The OCRR was leased to NYNH&amp;H in 1893. Note that the Housatonic road was leased to NYNH&amp;H in 1892, yet it does not appear on this map.  This implies that this map was released shortly after the 1893 acquisition of the OCRR.
