The Red Caboose

I found this little red caboose sitting by itself for no apparent reason on Hay St in West Warwick, 

I was just driving around wasting some time before an appointment and came across this red caboose, which says on it 'West Warwick Friends Of The Greenway' - I couldn't find any other explanation - but am thinking that maybe it used to run on the rails of the rail-bed that is now the bike path which is just a few yard behind the caboose.
