Normally when I amend an article, I only do this inline to the text and do not issue a separate notice about the changes which are typically minor. However, an article published earlier today contained a serious error which I have now corrected.

Many readers are notified about articles by email subscription, and they do not get notices of changes. This article is intended to alert them.

In my review of the evolution of new train requirements, I had flagged the big jump in train costs, but missed the November 2023 TTC report in which this was incorporated in capital plans. This produced my inaccurate surmise that the replacement trains for Line 2 might be affordable even without the requested Federal subsidy.

That was not correct, and for this I apologize to readers. That error is not up to my standards.
