neville,
If you did some further research you would see that
G&W bought the Adelaide-Darwin link in 2010
Caryle invested in G&W in mid-2012 investing $800m to help it buy RailAmerica for $2bn. It has gradually sold those shares over 2012 and 2013

UShaha,
JPMorgan "Nominees" is the key bit - it is merely a paper shuffler - basically it acts as the registered holder on behalf of a whole bunch of investment funds and superannuation funds who are the true beneficial holders.
It basically does all of the paperwork on behalf of the investment and super funds, and does not actually hold much power itself. For voting and the like it will act under instruction of the beneficial holder, who normally follows the recommendations of a few other firms.
Apart from Eddington being Chairman of the local branch of the Bank that owns this services company, I wouldn't read much into it,.
