The TTC board will consider a new report today that says it will cost $9.1 million to completely overhaul 30 aging streetcars and $25 million to maintain the rest of the aging fleet.

Last week TTC spokesperson Brad Ross announced that the city could expect Bombardier to deliver four new vehicles a month beginning in April.

Bombardier has failed to meet its TTC targets. At the moment, only 16 new streetcars are operating on city streets. Ordered at a cost of $1.25 billion, 73 of the new vehicles were supposed to be in operation by the end of last year.

Ross said last week that the delay means the TTC has to essentially “rebuild” old streetcars that were never meant to operate this long.

The TTC would have to reduce service levels if they don’t spend the extra money, the report says.

The TTC has filed a claim for $51 million in liquidated damages for the delayed delivery of the new streetcars. In the report, TTC staff say they expect the $34.1 million will eventually be recouped as part of that claim.

However it’s not yet clear when the TTC will see the money or whether they will receive the full amount of the claim.

According to the new timeline for their delivery, all 204 of the new streetcars are expected to be in operation by the end of 2019.
