Realtor.com currently shows two properties on or abutting the Monson RR ROW. 27 Chapin Ave, asking $125,000, is a recently remodeled former slate company house that abuts the north end of the Monson yard parcel, adjacent to the former Chapin Ave crossing on the Hebron Quarry Branch. The back yard also abuts the Monson Pond Quarry Branch ROW.
2 Greenville Rd. is a 1.3 acre lot for $27,000 that abuts or may even contain part of the former Hebron Quarry Branch ROW where it starts up Homer Hill. The tax map shows a quarry nearby, but I think it is just a pond.
Also, the Farrin Brothers lot, just east of the station parcel, was recently listed for $14,000 but no longer appears; it has not sold, as far as I know. This was the location of the garage often mistaken for the Monson RR engine house before it was burned down by the Monson volunteer firemen in a training exercise 10-15 years ago.
