If the electrification of Ronkonkoma's so overated, why did traffic on the line tripple the first year?
You can't attribute that to just the elimanation of the change at Jamacia.
They cut a lot off of the running time. Cutting 15 minutes doesn't sound like a lot to you, but it's a lot when it means getting home earlier each day, sleeping later each morning.
1/2 a billion dollars? The LIRR should demand their money back from EMD, it probbably would have been equal or LESS in cost to simply electrify the entire LIRR. And that's just the immediate replacement costs of the diesel fleet. We've not added in the costs of all the track dammage, bridge dammage, delays, failures, etc that the fleet's costing taxpayers.
The DE/DEs and C cars made little long term economic sense. They were simply an expensive way of putting off the inevitable. The days of running diesel on LI really should be behind us by today.
As for acceleration not mattering? The LIRR's existing schedules are nowhere near as agressive as they could be. In fact, a number of branches are down the almost as slow as they were in the teens and 20's, when the MP-54s were new. The MP-54s were <b>slow</b>, and couldn't break 50mph. Even the M-1s could significantly out accelerate them. There's really no reason for such slow schedules.
Electrics are great for curvy lines - they can accelerate out of curves far faster than diesels can. They're even better for lines with grades - electrics simply outperform diesel on lines with steep hills. This is standard 'boilerplate' information in any decent RR text in the motive power chapter.
The higher MAS doesn't mean anything to the diesel fleet. It's bragging rights. They spend so long getting to 80 that the time they spend at 80 simply isn't very long. I've taken them on the OB line. Once leaving Mineola, they take until New Hyde Park to get up to 80, and shortly thereafter, they slow for Queens. Once leaving Queens, they start accelerating, but forget it, they don't reach 80 before having to slow once again. Even a crappy set of M-1s can reach near 80 by Merrilon Ave, and certainly be at 80 before the turnouts between NHP and MA. They'll reach 80 after leaving Queens. It's no contest.
And, let's face it, the DE/DMs are slugs, pure and simple. And unrealiable ones, still. I've seen triple headers, long trains with one unit dead, 7 cars with one locomotive. Just go to Mineola some day and WATCH the traffic. You'll see failed units out on the mainline.
Electrify to Port Jeff now, do Oyster Bay, and out to Patchauge. Set a firm date to phase out diesel ops on LI, and sell the C cars and EMD's junk for scrap. It'll be much better for LI in the long term.
