Team Project File 2018 Agenda
Review preliminary station design with Maintenance/Ops, Metro
Transit Police, and Fare Collection.
Meeting Notes
1. H. Jaeger gave an introduction of design process and the
contributing factors to the development of the preliminary
prototypical station design.
Lessons learned from Hiawatha line A consistency of station
design along the Central Corridor line Ideas generated through a
series of design charrettes Integration of art into station
design
2. K. Williams gave a presentation of preliminary prototypical
station design
Review of center and split side platform zones (entry,
circulation path, shelter, boarding/unboarding)
Split side Configuration requires station identity begins at
intersection
-
On Day 1, two car train will pull to front of platform Ticket
Vending located at 1/3 points of platform Ticket validators and
Information kiosk located at platform entry Platform is concrete
with possible radiant heating. Possible use of waste
heat from Excel Energy.
Columns are concrete and possible art opportunity Rear platform
wall is glass and metal mesh resting atop 18 precast
concrete knee wall
Canopy is flat roof system of Kalwall panels with internal
drainage sloping away from platform edge. The flat roof provides a
good opportunity for the incorporation of solar panels to send back
power into the electrical grid during the peak electrical summer
load .
Canopy and shelter pods both have copper fascia Shelter areas
are glass and transparent as possible Inner track bioswale is a
possible option to mediate water runoff and
snow storage
Electrical and Communication boxes are located on platform. A
small enclosed area for use while working on electronics is
provided.
3. Maintenance/Ops Comments
Glass wall along the rear platform is a concern, but
transparency is necessary. Accidental glass breakage has happened
as a result of plowing. Central Corridors alignment is different;
plowing should be pushing snow in opposite direction of glass.
Weight and size of 3/8 glass panel will require more than one,
possibly three, maintenance personnel to replace.
The canopy roof system of Kalwall panels and solar panels is
acceptable. Rubber membrane roofs are not desirable due to short
life cycle and lack of durability. Copper roof is the best
solution.
Carefully review for ADA compliance; see recent audit No
interactive art work should be allowed.

Will canopy have internal drainage sloping away from platform
edge. (Yes). Will not have drainage issues found at Lake St
station.
Heat tracing is desired at all roof drains. Have on indicator
light. View of station from above needs to be considered. Top of
canopies
should be attractive.
Concrete platform is highly preferred over a paver system Dark
colored concrete is desirable to address the issue of ground in
gum
and general debris discolorization.
If radiant heated platforms are possible, it is highly desirable
and will help resolve issue of snow removal and storage
Rear 18 knee wall should be panelized for cleaning (joint
provides logical stop point for cleaning) and replacement
purposes
The detectable warning strip should be compatible with Metro
Transits developments
Best place for trash receptacles are wherever people congregate.
Cigarette butts are an issue.
Current station design provides adequate shelter Greenscreen is
acceptable if maintenance is minimal and maintains
aesthetic value
Discouraging platform access at non-designated entries with
fencing is important
4. Metro Transit Police Comments
Construction of shelters need to be transparent as shown 18 knee
wall is acceptable Signage directing pedestrian traffic to the
station is critical Endorses inner track fencing Trash receptacles
need to be open in case of explosion and should not
be underneath canopy. However, when open and unsheltered,
receptacles fill with water. Issue needs to be resolved.

5. Fare Collection
Two validators at each entry are needed at high use areas such
as UM, Snelling, 4th/Cedar. At other locations, rough in for a
second. Patrons have suggested validators be located near the top
of ramp for ease of use.
Have call box near ticket vending Clear demarcation and signage
of validators is required Sun glare make validators difficult to
read Validators must have audio cues for the visually impaired
Please advise of any errors or significant omission.
