Vancouver, B.C.
Following the assessment,
the first order of business was
to conduct a corrective grinding
program to remove the surface
damage and as many defects as
possible (some of the shells were
too deep to be removed by grinding).
The next order of business
was to concurrently re-apply the
target rail profile, which is designed
to perform with SkyTrain's
custom wheel profiles and work as
a wheel/rail system.
Ramped up rail grinding
While BCRTC regularly operates
an in-house eight-stone switch and
crossing grinder, it alone is not sufficient
to address the amount of
maintenance required of the rail
on the system. SkyTrain contracted
ARM, which brought in Loram
Maintenance of Way, Inc., which
operates an eight-stone production
grinder with higher horsepower
motors, to perform the initial
corrective grind (and the subsequent
annual grinding program of
approximately 40 shifts per year)
under the direction of an ARM
grinding specialist.
The initial corrective grind
focused on the Expo Line, which
had the oldest and softest rail on
the system and needed the most
attention. This was followed by
the Millennium and the newer
Evergreen lines. With the most
serious rail surface damage addressed
by the initial corrective
grind, BCRTC and ARM directed
their efforts toward getting the
system into a maintenance mode
and ultimately into a preventive
mode of grinding. A critical aspect
of the ongoing program is to fully
utilize the available work windows
to maximize productivity.
" Effective contract grinding
requires a collaborative effort, "

" The number
of grinding passes
required to restore
or maintain rail
is directly related
to its condition.
The need for
fewer passes is
an indicator that
not only is the rail
health improving,
but that we are
heading toward
a preventative
state, the goal
of all railways. "
- PEETER VESIK
said Peeter Vesik, BCRTC asset
integration project manager,
who, in his former role as technical
analyst in the Rail Maintenance
Division, coordinated the
contract and in-house grinding
programs over the past five years.
" We know that grinding is not
cheap. We're always looking for
ways to gain efficiency by trying
different methods, speeds and
stones to complete as much work
per shift as possible to maximize
our maintenance windows "
In addition to managing the
nightly grinding effort to ensure
that all defects that can be
removed are removed and that
the target profile and the desired
contact band are returned to
spec, ARM also advises BCRTC
on which segments of track are
most effectively covered by the
contract grinder and which are
best addressed by the in-house
