Stupid idea but to solve the issue of platform heights might they be using a pneumatic system to raise/lower the bogies to the correct height? Could be possible, but would be extremely costly I would imagine. |

And time consuming, don't forget the Cathedral - Park Square section of the network is already heavily congested enough as it is.

The latest news on this project is a cost of about £18m , 4 vehicles of standard European tramtrain design to be supplied by an unamed supplier . The trams would operate every 20 mins with 3 new stations including Rotherham Central . It would be fully intergrated with Supertram . Construction and vehicle build would start in 2013 and service would commence in 2014 .

Sounds like it will be incredible tight to maintain a 20 minute service between Parkgate and Sheffield city centre with just 4 vehicles, especially if one of these vehicles fails or is involved in an accident etc. I suspect that the regular Supertram carriages wont be able to run the service through to Rotherham? |

I susopect you're right. I suspect that the new vehicles will be diesel powered and there will be no catenary on the "new" section.

The vehicles will be powered by electricity from overhead catenary .

Wiring up the short nr lines to 25kv is a easy task, and if these trams are built using now standard 3 phase ac motors and inverter electronic controls, the swich from 750v dc is easy. There is no technical problems except plastform hight, the requuirement are the legal and safety case for light rail trams with street running and heavy rail running.
Cheesysmith.
ps- what is the platform high of supertram platforms? I know the manchester network would have no problems, as the first part of it`s network was actually heavy rail lines converted to tram use, so the hights are already at main line standards.

The vehicles will be powered by electricity from overhead catenary . And if I can recall correctly, once the infrastructure is in place, it will become a permanent fixture wont it? PS - could convectional Supertram vehicles make use of the Meadowhall - Parkgate line, if the platform heights are the correct size? |

I can"t see any reason why not .

I don't think that conventional Supertrams are built to "heavy rail" standard are they? If not then mixing "heavy" and "light" rail rolling stock on the same track would probably present a problem to the regulatory authorities ( there is no intention to cease conventional traffic on the line is there?) As for the reduction in numbers scheduled to be bought I would think it was on account of cost.

I know that the Manchester equipment is substantially 'beefed up' on account of it running, as it does, partly on 'heavy rail'.

I thought it was so far only confirmed that the £150,000 had been funded towards the feasibility study work, before any further action is taken? |
