However, further studies indicated substantial problems including the questionable feasibility of the elevators, the very negative impact on tunnel rail capacity and the unprofitability of the whole enterprise.

The Swiss Federal Council and the government of the canton of Graubünden announced in September 2007 that the project was put on indefinite hold.
