I feel so bad for that engineer that died on the same day he hit the cyclist, and the engineer that hit those two kids within 7 days, someone told me that one. LB, those pictures aren't that bad, I can clearly see the tracks, and I had no idea that the decoration around the station was important. So the most dangerous crossings were Unqua Road, Park Blvd, Bellmore Ave, Centre Ave, and Merrick Ave. Man that is close quarters from Sunrise Highway to the tracks (Don't even think about sticking your arm out the window kids!). Now LB, you mentioned you like the 2 photos of the LIRR crew cutting out the temporary tracks and connecting them to the new elevated ones. Does that mean for about a week or 2 weeks at the Bellmore-Merrick, Massapequa Park, and the A/C/L segments on their elevated station's opening day of service that while they were cutting in the tracks, that one of the temporary tracks was in service, while one of the elevated tracks was put into service? I know they did that at Rosedale, Wantagh, and Seaford. Also like you said, that when Amityville was elevated, the interlocking was also built, so that would put the temporary tracks starting just East of the Sunrise Highway trestle and the current substation.
On a side note I found out the measurements of the M-1 train cars in a diagram on trainsarefun.com (Both A and B cars):
85 Feet Long
12 Feet 10 Inches Tall (from top of the rail to the apex of the roof)
10 Feet 8.5 Inches at it's widest point across
50 Inches from the top of the rail to the bottom of the doors.
This is the train to (NYC). Stopping at: Babylon, Lindenhurst, Copiague, Amityville, Massapequa Park, Massapequa, Seaford, Wantagh, Bellmore, Merrick, Freeport, Baldwin, Rockville Centre, Lynbrook, Valley Stream, Jamaica, Kew Gardens, Forest Hills, Woodside, Penn Station OR Grand Central.
