Track rearrangement in railway tunnel in Montreal, was made difficult by maze of underground facilities, and by fact that work had to be performed under street between 2 buildings; aspects which necessitated freezing of water bearing soil for stabilization; freezing plant consisted of 2 electrically driven compressors circulating freon 12 gas through heat exchanger; diagram of freezing pipe system; its inner heat was sufficient to prevent freezing of concrete.
