3. Passenger Information Service 3.2.3 Help Points A Help point is designed to provide passengers with information via direct audio contact with the station control manager, supervisor or Customer services staff. Communication is by a two way intercom connected into the station communications system such that the call can be answered directly by the station staff on site or routed automatically to another station control room if the station is unmanned. The help point may contain a number of other systems such as a ﬁre alarm call point and an assistance call point. Irish Rail have developed a standard Help Point – this can be seen in the photographs. Siting and Ergonomics need to be carefully addressed. In general one help point per platform will be required – this would normally be sited near to customer information signs and the main entrance/exit from the platform. At its optimal height location, adults, children and MIPs must be able to comfortably speak into the grille and operate the large buttons.
2. Model Station - Objectives & Planning 2.3.8 Stair Design Height of help points should be accessable to adults, Stairs are to be designed in accordance with the Irish National children and MIP. Disability Authority Handbook (NDAH). Stair Dimensions Preferred dimensions for risers and going are 150mm and 300 respectively – these values are to be used subject to tolerance for the rising to suit the site conditions and levels. Nosing proﬁles should be avoided and open treads are not to be used. Single stair ﬂights are to have a maximum of 10 risers with a landing length of at least the width of the stair. Note that it is only permissible to have two ﬂights in a single direction so that a typical stair rising in excess of 3m will require a change in direction. Staircase widths within passenger areas are to be a minimum of 2 metres wide. If stair widths are in excess of 2.4 metres wide a central handrail is to be provided.

Handrails Handrails are to be located on both sides of the stair and are to be positioned between 840 and 900mm above the stair pitch line. Handrails are to extend a minimum of 300mm beyond the top and bottom riser. Handrail proﬁles are to be 45/50mm diameter and located 45mm away from wall surfaces. The ends of the handrails are to be returned in towards wall surfaces to avoid coat sleeve etc becoming hooked. A lower second handrail is to be provided at 700mm above the pitch line where appropriate. A single handrail at landing levels is to be provided at 1000mm above ﬂoor level.

Balustrading The widest permissible gap in any stair or landing balustrading should not permit a sphere of 100mm diameter to pass through. Customer Information A continuous upstand of at least 75mm is to be provided at all landing levels. Tactile strips to External Stairs An 800mm tactile strip is to be provided at the bottom and top of each staircase this should be located 400mm away from the bottom and top riser respectively.
2.5.1 Platform Design The platform width is to be a 3metres with the minimum width of 2metres where obstructions exist. Platform surfaces must be slip resistant and have a cross fall away from the track edge (no greater than 1:40) to prevent surface water ponding and reduce the risk of andobjects Safety Equipment rolling on to the track. At the ends of platforms appropriate signage must warn passengers not to venture on to the track. Where it is anticipated non-stopping trains will pass through the station a yellow line 1metre away from the platform edge is to be painted and station announcements made to inform passengers of the pending train.
Platform paving/ﬁnishes Platforms edges are to have a 800mm tactile strip located 500mm back from the platform edge. 2.5.2 Platform planting Platform planting is to be encouraged where appropriate. Planting schedules should provide year round colour and variety and also require low maintenance. 2.5.3 Platform Furniture – see also Components The following furniture is required on all platforms, seating, passenger shelters, litter bins, station help points, ﬁre cabinet, smoking area with bin and travel information posters. 2.5.4 Platform Train Interface (PTI) All platforms where the platform edge is not level with the train carriage ﬂoor are to be provided with a mobile ramp unit, which will Model Station be operated by the station staff.

Station Design Study and Model Station prototype Working in conjunction with Aukett, a multi-disciplinary architectural practice based in London, BCDH completed the research into products and developed a design for a prototypical railway station and consistent standards to be applied across the existing station network.
