Passing Track Plan<br />

Without additional<br />

infrastructure<br />

improvements, may<br />

constrain ability to increase<br />

frequency of local trains to<br />

accommodate future<br />

growth.<br />

Blue Line and Orange Line<br />

customers.<br />

Year 2030: 2.9M express<br />

riders<br />

may wait at stations while<br />

express trains pass.<br />

Maintenance on shared<br />

track can be done either on<br />

late night shifts or on<br />

weekends.<br />

Train schedules may have<br />

to be modified to minimize<br />

service reliability impacts<br />

for Blue and Orange Line<br />

customers.<br />

8<br />

Year 2030: 3.1M express riders<br />

plus opportunity to improve<br />

ordinary service and enhance<br />

ridership in Blue Line corridor<br />

Lower potential for operating<br />

delays due to largely separated<br />

operations. Sustained higherspeed<br />

operation. Enhanced<br />

schedule reliability for express<br />

and ordinary trains.<br />

Overnight maintenance on<br />

separate alignment should not<br />

interfere significantly with<br />

express or local operations.<br />

Opportunity for limited-stop<br />

local service benefiting existing<br />

Blue Line customers. Improved<br />

reliability for current CTA<br />

customers.
