Assuming no objections are raised before the December 24 deadline set by the STB, the voting trust that has controlled RailAmerica since the transaction closed on October 1 will be dissolved on December 28. Thereafter GWI would assume control of RailAmerica and begin integration of the two companies.

The completion of the $US 1.4bn acquisition, which was first announced in July, means GWI will operate 108 railways in 37 US states and three Canadian provinces covering more than 19,000 route-km.

GWI says the takeover will strengthen its ability to serve industrial customers and Class I railways while yielding significant synergies.
