The Oyster Bay group has 4-6-0 #35, while the RMLI group in Riverhead has 4-6-0 #39, the last LIRR steamer to run in revenue service (1956 end of steam ceremony ?). I haven't kept up, but I thought that #39 was further along in the restoration process, i.e. the boiler had been inspected/serviced/repaired. There used to be talk of running #39 on excursions out to Montauk with old 2900 series coaches, but it doesn't sound like the FRA would allow the G-5 out on the main line. My info is not current, however.
