Horse Tram Problems

Summary

The request sought correspondence regarding commissioning problems with horse tram points on the Douglas Promenade, and the authority disclosed all relevant information including design disputes and contract instructions.

Key Facts

• The proposed tram alignment was initially deemed unsuitable from a highway perspective in December 2018.
• A compensation event was notified in October 2021 regarding the instruction to send motor points to TSUK for factory fit testing.
• In November 2021, a Project Manager's Instruction removed tram rail works between chainage 1060m and 1150m from the scope.
• Technical discussions in early 2019 revealed that achieving a 1 in 7 gradient for all points was not practical for locations HS2 and HS3.
• Burroughs Stewart Associates proposed standardizing the problematic points to a 1 in 4.5 gradient.

1. The use of the 57R1 came from a report commissioned by Isle of Man Railways, from Manchester Metropolitan University, Rail Technology Unit, March 2012. It is particularly relevant where tight curves are required such as at the points.

2. 8th November 20118 and 24th January 2019: Meeting held with Transport Services to discuss the rail requirements including blade geometry, IL requested 1:7, this resulted in the need to demolish the northern most wall to the sunken gardens, and amendments to highway design. IL confirms that he would like the points north of the works to be ordered at the same time, note 15, subject to a separate order.

3. 12th February 2019, comments received from IL on the draft notes of the meeting, which were amended and then issued.

4. 9th April 2019, email TOM to KP and ACB raising design queries on the S&Cs, forwarded by ACB to IL.

5. 10th April 2019, IL responds and ACB issues response to TOM.

6. 2nd September 2019, ACB issues drawings received from TSUK of the points to IL for comment. Drawings comprise DBHT / MER Wheel Rail Interaction, Turnout GA – HS1 Douglas Tramway (2 sheets), Turnout GA – HS1 Comparison Douglas Tramways S&C, Technical Note: Douglas Bay Horse Tramway Wheelset Interface with new S&C Design for MER Vehicles.

7. 11th September 2019, IL replies, raising concerns, in particular about the compatibility of Horse Tram wheels and MER tram wheels

8. 12th September 2019, of SCUK following a meeting with IL sends an email to TOM, copying the mail to IL, confirming that the wheel sets will be based on MER and that if required IL would modify the 13 Horse Tram wheel sets.

9. 13th September 2019, IL emails TOM and confirms, “I agreed that this is the most cost effective and practical way forward.”

10. 16th September 2019, TOM confirms to ACB that he will “…..take Ian’s comments as approval and proceed accordingly.”

11. 2nd July 2021, IL to ACB advises that the point work at Castle Mona is not normal for a street tramway.

12. 12th July 2021, ACB responds in detail, expressing his concerns.

Redacted 13. 12th August 2021 ACB through IL coordinates a meeting held with the Rail Regulator. At the meeting explained why the gap should be the width of the groove, and this was appreciated. The Rail Regulator expressed his concerns at the width of the gap, explaining that it may result in the horse’s hoof being caught, and asked for it to be reduced to 40mm.

1. 24th August 2021, issues notes of the meeting

2. 07th September 2021, in an email advises that there is no standard width for points but that they would not usually less than the groove. Redacted Redacted Redacted
