Rail configuration designoptions have different costs,advantages and burdens. Wemust remember that the AMTproposes to run a lot moretrains through our Town, andwe do have a say. Let’s try tounderstand what is at stakeand then get involved toobtain the best solution forour Town, whose founderswere railway leaders whonever compromised the inter-ests of MW.
What it involvesThe new rail scheme will
involve a vertical separationof the vehicle road bed fromthe train rail line. All informa-tion we’ve seen suggests thatthis would entail excavating atrench which would lower therail tracks in order to allowvehicles to pass over on somesort of bridge structure. Thefollowing guidelines from theAREMA manual for RailwayEngineering would need to berespected (the AMT specifica-tions should be very similar):• Approx. 23 clear feet isrequired for train clearance(top of rail to underside ofstructure above);
• Minimum width of 3 raillines would be approx. 40feet;
• Maximum grade forembankments would beapprox. 45 degrees;
• A heavy rail grade would begreater than approx. 1.8 %.There are various ways to
accomplish the new rail androad structure configuration.At the risk of oversimplifyingthe problem, the accompa-nying sectional sketches willillustrate what a tremendousimpact this project will haveon our Town.
Section ASection A depicts an Open
Trench (30 ft. deep) withbridge at grade (no hump).
The distance between thestart of the slopes on eachside would be +/- 100 feet. Inour situation it would start atthe sidewalk on SherbrookeSt. and reach the sidewalk onBroughton for the full dis-tance between Westminsterand the existing train station,extending approx. 1500 feetfurther in both directions. Ifthe trains are powered bydiesel electric motors, theexhaust discharge would be atstreet level. A six-foot highfence would close off theentire depression and onewonders how they wouldaccommodate a train station.This is a relatively inexpen-sive solution, but a lessexpensive approach (SectionB – Open Trench – Bridge 10ft. above grade) is even moreoffensive aesthetically and inits encroachment footprint.
Section BSection B shows a humped
bridge overpass in order tomeet the minimum clearancesfor a shallower trench. The
bridge ramps could begintheir incline on the north sidenear the video store and onthe south side near theCommunity centre. If anyonehas a problem conceptual-izing this design, you onlyhave to stand on top of the“hump” bridge onWestminster North and lookdown. Clearly the Towncould not tolerate being splitthrough the middle of itscore. Regretfully, this solu-tion was imposed in the pastand it cannot be allowed tohappen again.
Section CSection C – Covered
Trench, the safest solution(especially considering thevery large number of trainsproposed), shows a straightstructural walled trench cov-ered at grade for the entirelength of the passage throughTown, rendering the trainsand tracks invisible. Accessto the station platform belowwould be integrated into thetrench structure. The use of
the covered surface wouldprobably be a negotiationwith the railway, but optionsinclude green space, parkingand even small buildings. Thearea reclaimed betweenWestminster and Brock (areapresently occupied by raillines) is approx. 60,000square feet. Among otherrequirements would be theprobable need for existingdual fuel technology (dieseland/or electric) or simplyelectric powered locomotives,a concept being promoted byPeter Trent, the mayor ofWestmount. This Option C, inaddition to being the safestsolution, is clearly the onlyoption that ensures theintegrity of the Town core.
Make our needs known;get involved
The covered trench,Option C, is the progressivesolution that is in everyone’sbest interest: it offers safety,aesthetics, an elegant accessto the train platforms, andresponsible urban develop-ment. We cannot afford tosell ourselves short. Getinvolved in the Town discus-sions and support our electedofficials in their battle todefend our interests!

The future of the quality of life in MoWest is on the line. The AMT commuterline proposal regarding the projected augmented rail service presents theopportunity to improve our centre of Town or ruin it aesthetically andrestrain it economically, depending on the solution chosen.
