On the shared track
Penn Line: about 135 min of delay from faster trains passing.
21 passes held 15 trains this week, most often near West Baltimore.
An estimate, from how often a late train passed and the typical delay that follows — a pass does not always slow your train.
The number in each cell is the share of trains on time that day — higher is better. The background colour grades that same number, so each row reads at a glance.
- 85%+ on time
- 70–85% on time
- 55–70% on time
- Under 55% on time
