2017 Leaf oil season starts
Posted by blue streak 1 on Thursday, September 28, 2017 9:54 PM

MBTA announces start of fall 2017 leaf oil campaign.  This is first announcement by any agency for this year.  BTW never have heard about Amtrak but they must do as well especially on less traveled routes ?

I don't think I've ever heard of anyone but transit agencies work on fall leaves.  I think this is because commuter rail schedules rely on high adhesion for acceleration and deceleration.  With much longer runs between stops, Amtrak doesn't have this problem.

It’s a big deal in the UK where the leaf fall espically on the south of the Thames Network can cause significant timetable disruption. NR has spent millions trying to find a good anti leaf strategy. One of the most effective is summer application of the chain saw.

Whatever became of the vaunted GE ‘supersonic’ rail washer that was, supposedly, very effective even at high peak road speed at eliminating this plastic-like film?

{Quote:) In lieu of the changing season, Keolis Commuter Services (KCS) will perform rail-cleaning services on Massachusetts Bay Transportation Authority (MBTA) rail to reduce slippery rail. (End quote)

I think they used an incorrect word. "LIEU"  is defined as "instead of". Should have said Due to the changing season....

No-one proof-reads anymore.

Seen any of the on-line versions of newspapers lately?  Oh brother...

Went the way of all the other miracle solutions to the problem many mouse milk based. The most comprehensive evaluation of potential solutions has been conducted by Network Rail. Not sure how much of this work has made it into the public domain.

In many cases they proofread - they just don't understand the meaning of the words being used.

Probably parked next to the hybrid locomotive....

Aren't all the locomotives currently in use (outside of straight electrics) hybrids?  Diesel electric and all.

We've been through this.  If it doesn't have energy storage in the transmission, it isn't a hybrid.

Note that this applies to dual-modes as well, even those that hypothetically can use third-rail or overhead power in parallel with electricity from the onboard generated power.  (Or, in my personal opinion, inductive power from lineside sources that is used directly and not to charge a battery or supercap bank, spin up a flywheel, or pump up pressure in an accumulator on board, although some definitions of lineside storage differ with mine)

The big thing about the GE hybrid was its battery chemistry and construction (there is as mentioned in previous old threads a discussion of these in, of all places, the publications section of the COMSOL multiphysics software company. 

It's more likely that the 'missing' rail-cleaner is parked ON the hybrid locomotive; it isn't very big and as I recall it doesn't require much tankage or cabling.

Stored braking energy is what makes a hybrid.

You're telling me!  One of my pet peeves is the common use of the word "decimate" instead of "devastate."  They don't mean the same thing, as any veteran of a poorly performing Roman legion would tell you.
