A rough count:
Sixteen standing Roundhouses:
B&M - Troy - Reuse by non RR company.
BR&P - Rochester - Reuse by non RR company.
DL&W - Binghamton - RH+TT both abandoned/derelict
Erie - Port Jervis - (RH current use?)
G&W - Retsof - Still in use by G&W/R&S (oldest NY state RH in continious RR use?)
LV - Auburn - Reuse by non RR company.
LV - Manchester - abandoned/derelict.
LV - Cortland - Reuse by non RR company.
NYC - Utica - Reuse by non RR company.
NYC - Batavia - in use by GVT railroad. (non-RR use from 1950's until 2008)
NYO&W - Rome - Reuse by non RR company.
PRR - Sodus Point - Reuse by non RR company.
PRR - Ebenezer - Reuse by railcar rebuilder company (only NY site where both TT and RH still in use?)
PRR- Olean - Reuse by non RR company.
Pullman company - Buffalo - reuse by non RR company.
South Buffalo Railway - Buffalo - in use by South Buffalo (G&W) railroad. (like Retsof, also continious RR use to this day)
Only three roundhouses still in use by Railroads today (Retsof, Batavia, South Buffalo) (none have remaining TT's)
Only two that have been in continious RR use (Retsof and South Buffalo)
am I missing any?
Doesnt LIRR still have a roundhouse in use?
Five turntables in use:
Canadian Pacific - Binghamton - New TT built in 1990's.
Erie - Hornell - historic Erie TT in use by Alstom.
D&H - North Creek - historic D&H TT in use by Upper Hudson River RR.
Erie - Port Jervis - historic Erie TT in use by New York & Greenwood Lake Railway
PRR - Buffalo (Ebenezer) - Historic PRR TT and RH in use by railcar rebuilder company.
(PRR Ebenezer is the only NY site where BOTH the RH and the TT are in use today?) (LIRR?)
(I thought I read somewhere that Long Island RR still has a TT and RH in use..is this true?)
