Slip/Slide This Season?

Post by Patrick A. » Tue Nov 16, 2010 10:15 am

How has the slip/slide conditions been on the territory this year? On the New Haven Line it looks like the leaves haven't impacted travel much as none of my trains have had any trouble.
I have lived to ride on the M8.

For the whole week about a week or two ago I remember my upper Harlem direct train having some very rough stops, particularly at Goldens Bridge and Croton Falls. It sort of felt like an equivalent of ABS for a car with the brakes rapidly engaging and releasing accompanied by a loud air hiss. Is that a typical symptom of slip/slide or likely something else?

Yes, that is an indication of the problem.

Last week, one of my morning trains, went past six stations. We kept having to backup.

It's been a typical fall season so far. Haven't had anything really bad so far on my trains, but heard a few other guys sliding all the was past stations here and there. A few years ago was really bad until they updated the software on the M7's.
Hurry up and wait at the signal!

Is slip/slide more troublesome for MU's or diesel hauled equipment?

The diesel equipment usually fairs a lot better because they are equipped with sand, but nothing is guaranteed depending on weather patterns and how many leaves are grounded already...so far it's been fairly mild in comparison to past seasons.

I guess there haven't been as many flat spot OOS issues as in the first year(s)? Or do they have more capacity for quicker fixes now?

With the new software in the M7's it has been far less of an issue since then and less cars are O.O.S because of that.

I'm noticing more cars on the NH Line have very loud wheels. I guess there is only so much MN can do about slip/slide as it has been a problem to railroads the world wide since the first trains ran on rails.

actualy the problem only started since introduction of composition brtake shoes.
the cast iron shoes never had the slip slide problem
If Conductors are in charge, why are they promoted to be Engineer???

We ran the old MUTS and the 4400's on the New Haven with no slip/slide problems for years. As Dutch stated, it is the brake shoes. When they started using composition brake shoes they jacked up the brake cylinder pressure but of course I have been away for a while now so I am not sure exactly what the situation is today.
I could tell some more stories about this but not tonight.

cast iron shoes make the wheel tread rough, the composition shoe polishes the wheel.
A composition shoe also has a higher friction rate, therefor grabbing the wheel.

Funny you should mention the slip/slide. On 1530 this afternoon, only the first car was supposed to be off at Green's Farms, but because of the slip/slide they couldn't stop so they took the second car off as well.

Last night's storm seems to have made rough going on the Harlem today. 953 completely missed Pawling and had to back up this afternoon.

My train has consistently overshot stations between Harrison and Stamford over the last week or so.

Cut some trees back from the ROW and you won't have this problem create such an impact on operations. Oh wait, MN can't/won't spare crews to go out and cut trees. Never mind.
