SIR diesel service

Post by jt42cwr » Tue Oct 27, 2015 6:12 pm

In the press release below issued back when the BL20GHs were new it states that
they may even be used to haul passenger cars to maintain limited service should there be a temporary third rail outage
.

How often does this happen in reality, and if it does, is there any way to know in advance when this is likely to occur? I.e. is it publicised anywhere?

I've never seen it happening myself but there's a youtube video of it. I don't know how often this happens and this is the only time I know of it happening.

Yeah, had seen that video. I was wondering more along the lines of scheduled maintenance.

I'm not sure about that, this is the only time I've seen them in use on the SIR. Someone else might have more information on that. All I know that is they don't publicize when this happens (unless I haven't been checking the MTA's website enough).

How can you operate the doors without 3rd rail power?

The locomotive's HEP should cover that, along with providing power for lights and HVAC.

Believe these units are not rigged for HEP,battery power could open 1 door leaf per car,figure that the 3rd rail was live,
but snow that deep could tear up the R-46 traction motors,needing the tow with the diesel

Is it possible that was a non revenue move and just to keep the line clear and relocate equipment in the snowstorm?

The train was stopped at a station for a decent chunk of time.

SIR's Brookvilles are BL20G's...no H...therefore no HEP.

Non-HEP locomotives can still provide it - the LIRR worked that way for years. Just siphon off some of the prime mover's power for hotel power.

The few LIRR MP-15's were modified to provide 600 VDC HEP for up to 3 cars of MP-75's turned into coaches,were
basicly rolling generators,could be used as control units in push mode.
There're NO known Mods to the SIRT R-46's for any form of HEP,only what was needed to operate of SIRT trackage,
they were Subway cars,running in tunnels or on elevated trackage with minor snow exposure,now running on ground level
SIRT trackage with snow that can enter traction motors fairly easy(ie NOT weather proof).
Was safer to tow the sets with the BL-20's instead running on their own and Short out due to snow ingestion.

Just needs to lick his fingers first.
GE, not EMD, makes the best locomotives now; has for over 20 years. Get over it.
