AREMA, the American Railway Engineering &Maintenance-of-Way Association, isdedicated to the technical advancement of railway infrastructure.
Earlier this year, Norfolk Southern made apresentation at an AREMA seminar, thatpowerfully illustrates all the problems withKelsan’s TOR lubricant and Portec’s bar technology.
We could not make a better competitive case.We invite you to review the followingunaltered Norfolk Southern presentation.

Causes - Transfer Mechanism
Material is picked up by the front face of the passing
wheels and deposited around the tread.

To achieve the desired coefficient of friction, the material
must dry quickly. This results in a skin forming around it.
Causes - Material Properties
8/14/2019 A Competitive Analysis, V2
http://slidepdf.com/reader/full/a-competitive-analysis-v2 19/28
Causes – Crowned Head Profile
• Harder for wheels to scrape
away dried or skinned over
material.
• Increases the potential for backflow due to material skin.• Decrease the potential for
backflow due to seal damage.

Quality
Products should be designed and engineered correctly from the
beginning. Poor quality is costly to both the buyer and seller.

Quality
Products should not be overly complicated to use and
should address customer concerns and requirements.

Quantifying Benefits
• TOR reduces lateral curving forces,
offering the potential to save fuel and
extend rail life.
• These benefits cannot be “guessed”
at, but must be factually supported andstatistically proven.
• Careful and accurate modeling must
be used to “extrapolate” these benefits
to large scale implementations.
• Benefits must be expressed in metrics
that engineering and financial
departments understand.
• Benefits must be monitored and re-
validated
