From my mailbox this morning - a suggestion that the Tram Train be used on the Portishead line.   There is more meat on the bones of that suggestion; looks like it will get a study.   Good or bad idea?  Could you (dear reader) be more positive if it attacks funding from beyond the West of England and / or shares Sheffield technology to help make it affordable?

Clearly that would be impossible! How would the tramtrain know whether it was a train or a tram when it got to Quays Avenue? If it was a train, it could not possibly proceed any further (even at 8km/h) because that would involve crossing a road, which as we know would be outrageously dangerous; if it was a tram then it could happily run down the middle of the road without a care in the world. Its poor electronic brain would output error code 42, and then shut down.

RAIB have responded to the accident on the opening day and to another one in November at the same junction. Neither merits a full investigation, but two in one place so quickly has led to a published note and a letter to the council:
Noting that two similar accidents have occurred in a short timespan at the Staniforth Road junction, the RAIB has written to the Chief Executive of Sheffield City Council advising that a risk-based review of this junction and the road traffic signals is carried out, and that prompt action is taken based on the findings of this review. The RAIB also noted that the positioning of a pole supporting the tramways’s overhead power supply wires had the potential to worsen the outcome of the accident of 30 November 2018. The RAIB has also written to UK Tram, which is the trade body representing the UK light rail industry, and responsible for providing guidance to constructors, operators and maintainers of such system. The RAIB has suggested that UK Tram consider whether guidance for the placement of such supply poles in close proximity to roads which cross tramways is required. The RAIB’s letter refers to guidance on this subject which has been issued by a French government body, the Service Technique des Remontees Mecaniques et des Transports Guides
