3.11.3.6 The Use of Glass In Stations
The following must be considered when proposing glass in or adjacent to public areas in
Railway Stations
• Maintenance
– Cleaning
– Replacement
– Repair (including to enclosed elements) – The effect of means and likely frequency of maintenance on operational cost
– Security & Safety
– CPTED/passive surveillance
– Vandalism – impact – kick – propelled object
– Vandalism – scratch
– Blast
– Accidental damage
– Screening or enclosure (to prevent unlawful access, exposure to danger etc)
– Structural stability / crowd loading
• Passenger comfort
– protection from weather
– thermal effects
– enable natural light entry
– enhance the quality and perception of the space
In partial consideration of the above, the following rules have been formulated for all new
installations at Railway Stations:
All glass must be annealed laminated with 1.5mm PVB interlayer
• All glass within a public reach zone is required to be filmed to prevent scratching
vandalism
• Where glass is exposed to sunlight it is to be Pilkington “Evergreen”
• All glass must be fully framed (4 sides) with minimum 35mm rebates
• Max dimension of any glass pane 1.2m x 1.2m
• Glass located where it cannot be be accessed by ladder must have a means of
access for maintenance (cleaning and replacement) agreed by RailCorp and be
economically justified by life cycle costing
• No glass will be allowed where it requires a track possession for maintenance
(cleaning or replacement).
• No glass will be allowed below 900mm on lift shafts, to limit the effects of impact
vandalism on lift downtime
• Glass below 900mm in other than lifts shafts, will only be allowed where sight lines
are required to facilitate passive surveillance, justified by risk assessment and
agreed by RailCorp
• No opaque glass will be allowed unless fully bonded to a solid backing
Glass should only be used where
• required for passive surveillance
• provides a demonstrated environmental improvement by enhancing:
– natural light
– perception of space
The onus is with the designer to demonstrate these benefits for RailCorp’s acceptance.
