Mayor Rahm Emanuel and CTA President Forrest Claypool were scheduled to kick off an expansion of the program that gives ex-offenders a second chance with rail and bus apprenticeships Wednesday.
Under the expanded program, bus apprenticeships will last up to a year while rail assignments will continue for nine months.
High-performing apprentices will be eligible to apply for full-time CTA positions.
As many as 200 bus positions will be included in the program along with 65 rail slots.
