There, I've saved them the bother of expensive consulations and research.

Dolorous but true!!

This is the report if your interested.

Some interesting things will be decided at that meeting, namely the rubber stamping of continued bans on bicycles and motorised scooters on trams, also update on current progress of HS2 studies, Northern RUS and the Rail station accessibility project/

If they put in overheads for trams on rail routes (which I assume they will need to) at 750V (am I correct?) then does that not mean that they then cannot electrify the route at 25kV in the future? As in if the MML is electrified and they then want to extend the electrification to Leeds, then surely routes are limited as the route is electrified at a different over head voltage.

Well it would mean the OHLE would need changing in future. Sure there was a thread about dual voltage overheads recently, that may be the solution?

Yeah if they put in 750v overhead as their doing in Sheffield then if they wanted to electrify the line for 25kv trains they would have to replace it, though some savings from supports, National Grid connections (though transformers would have to be replaced), etc.

Alternatley would be more expensive 25kv off the bat and build dual pickup tram-train rolling stock to operate on it. Though they may be able split the costs of electrification between Network Rail/local transit system.

The European idea of a tram-train is one that can run on both heavy rail and light rail tracks. Many are dual powered (AC/DC or diesel/electric.)

There are some routes that would be ideal for these, subject to a second city crossing in Manchester:
* Northwich to Sale to Manchester Victoria
* Rawtenstall/Heywood to Bury to Manchester Piccadilly
* Warrington to Cornbrook to Manchester Victoria
* Rochdale to Oldham to Manchester Piccadilly.

However, if GMPTE are just thinking of using them on routes like Rose Hill Marple to Manchester Piccadilly and not involving them on both light and heavy rail then they will make the 1980s order of Pacers look good in comparison.

Their thinking of them for some heavy rail routes where NR wont offer any more paths or where their major bottlenecks due to signalling. One particular route they mentioned as Tram-Train in the LTP consultation was Altrincham-Stockport, this could be an extension of Altrincham service and East Didsbury (Stockport if extension built) to form a circular.
