Rich, I know that your current remit on the Oldham line does not cover the later part of the route, but as a Site Engineer, you may have been fortunate to have seen ground stability results for the whole route.
The question asked by my wife who has an interest in geology of this part of the area, is were any ground deformation problems in the area between Shaw and Milnrow.
I am afraid I couldn't answer that question as I don't have anything to do with OR3, as you have noted. I will, however, have a look at our DMS to see what I can find...
Rich, can I ask a question of you as a site engineer. Through the former Dean Lane station, there is going to be a similar situation as currently found at Navigation Road on the line to Altrincham. There will be one line of heavy rail serving the waste depot with its container traffic to the depot just on the other side of the bridge at Reliance Street and there will be a parallel single Metrolink line that will serve the single platform.
How will the single line section on the Metrolink cope with the frequency requirements of two-way running before the single track Metrolink section and then after it. Will there be any need for Metrolink drivers to know if any container train is coming out of the refuse depot?
Although I don't know the detail, I understand that the design of the track around Newton Heath & Moston stop is capable of handling the traffic frequency. Remember that at peak, trams are every 6 minutes in each direction, so the timetable will probably allow a tram going in each direction into the stop every 3 minutes or so. Don't take that as gospel though...
With regards to tram drivers being informed of freight movements, I couldn't honestly tell you. Although, I know for a fact that the two infrastructures are to remain completely separate and the clearances between the two will be such that trams and trains pass one another without interference. So I would suggest the answer to your question is no. But again, that is purely speculation on my part.
Sorry I can't give you more solid answers.
