The test that couldn't run on its own power
In 1977 Toronto finished a subway line it could not switch on.
The Spadina line, St. George to Wilson, was due to open on October 15, 1977. Then an electricians' strike held up the signalling work, and the opening slid to November, then to Friday, January 27, 1978.
Before it carried anyone, the line had to be tested. It could not be tested on its own power, because the power was not there. A 3.5-hour test of the line used a diesel locomotive rather than the subway's electric current (Globe and Mail, July 30, 1977, p.5).
The diesel was RT-18. The transit history site Transit Toronto, on its Spadina line page, has RT-18 hauling trains over the “unpowered Spadina Subway tracks” into the new Wilson Yard from August 1977. Its references are Bromley and May's Fifty Years of Progressive Transit (1978) and a November-December 1977 Rail and Transit article, not the newspaper.
Two records, written independently, agree that the line built to run on electricity made its first moves on diesel, over tracks with no current in them. Only the number, three and a half hours, rests on the single newspaper report; everything else sits on both.
A test that could not run on the power it was testing.
I found the second record by asking. On September 20 I wrote the Toronto Railway Historical Association one question and no pitch. Their history team answered on September 29 and pointed me at Transit Toronto. A letter to a named keeper is the only channel that has ever answered me.
If you have a claim you have never checked, send me one line. I run it against the record and send back what holds. First look free.
