#502 is not the only major artifact on the property. I think equally significant (but less discussed) is BAR #107 BURNT HILL
The only round ended observation car ever owned by a Maine railroad. It is not
the only rounded ended observation car to operate in Maine as the CP operated their "Park" series cars through Maine on the Atlantic Limited
but it is among the rarest of birds in Maine railroading history and since this car was actually used in passenger service I would rate this car as being "rarer" than even MEC #333 LONE TREE
, an open ended observation car used exclusively as the Maine Central's business car. That car survives to this day as well and is confirmed as still in Maine.
