The Platform Train Interface Working Group last met on 15 September 2021.
PTI-WG discussed the programme to fit tactiles to operational platforms, with some members voicing concerns about the quality and suitability of some products. The group recognised the opportunity to collaborate, share learning points and influence the programme to ensure that any sub-standard approaches are avoided. This item will remain as an agenda item for future PTI-WG meetings.
- T1211 – Defining the requirements for remote connectivity for train dispatch
RSSB updated the group on the T1211 project which aims to understand the practicality of enabling remote connectivity of the TRTS / CD / RA equipment. To determine if a compelling case exists for specifiers and funders the project will involve an economic evaluation and a risk. York station is being used as a case study due to a variety of scenarios available for consideration. Real data is being used to estimate the performance and safety benefits that portable equipment could provide on the network. The long-term cost benefits for the next 10 years are estimated at £772k for York station, and the 20 years cost benefits are estimated at £1.31m. These results are encouraging suggesting a network cost saving of £3.5m and station level cost saving of £139k. Final project deliverables will be published early next year. The work will support a consistent industry-wide roll out, reduce costs to procure a solution, and aims to improve overall safety and performance during station operations.
- T1257 – Defining safe and efficient methods of working for conductor-controlled door operations
During the Covid-19 pandemic passenger numbers fell to 10% of pre-pandemic levels, dwell adherence did improve but not above 85%. Research by Northern Rail showed that for class 195 trains the method of work from wheels stop to wheels start took 45 seconds on average. In places with dwell times of 30 seconds we will never meet them. T1257 will investigate methods of working for guard-controlled door operations to identify the real time it takes to discharge methods of work. It will capture good practice from across the network to improve efficiency, whilst maintaining safety. RSSB updated the group on the project, which will investigate methods of working for conductor-controlled door operations considering:
- Activities undertaken during train arrival, dwell and departure from stations
- All physical and mechanical processes
- Activities undertaken directly by the conductor
Analysis will consider the risk profile over the entire method of working to identify where and if efficiencies can be made. This project will not consider changes to roles and responsibilities only efficiencies to current methods of working. The project will be published in autumn next year.
The Chair of the new Stations Working Group, Alasdair Forsyth (Great Western Railway), updated the PTI-WG on this newly established sub-group of PTSRG. The first meeting was held on 19 May with a good diversity of experience within group members. Areas of activity were agreed as:
- Use of escalators & stairs
- Assault & abuse and Accessibility (in collaboration with other industry groups)
- Station safety risk evaluation
- Passenger awareness while use of headphones and mobile phones
- The emerging risk of E-scooters
The scope of the group was discussed with a strong feeling that the passenger’s end-to-end journey through the station should be considered. There may be some crossover with the PTI-WG work, as it is not always clear where the concourse ends and platform begins. The next meeting is the Stations Working Group and the PTI-WG annual joint meeting on 24 November 2021.
- PTI flow modelling for pre and post pandemic - Ratesetter+
The University of Sheffield updated the group on Ratesetter+ which has been working on understanding how social distance alters passenger flow at PTI or stations, and what this means for service performance. The work has been validated by comparing real-world PTI flow time with that predicted, including the rise in passenger numbers. Social distancing has been well maintained prior to train arrival, but rarely during boarding and alighting. So, there is little impact on PTI flow times caused by the 1m social distancing rule. But the rule does cause corridors and bridges to become congested at lower headcounts than normal. Further work is considering passengers with luggage, people travelling in groups, busier situations, and those who have decided not to travel by rail. Future work will consider what we can learn and take forward for longer term application to understand the PTI better.
Next meeting: 24 November 2021
