Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a recent change. Has there been any significant system upgrade or process change in the last 1-2 months?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, a new routing algorithm was implemented. Impact on approach: If confirmed, we'd focus on the new system's performance and integration.

• Considering the scale, I'm wondering about the scope. Is this 15% drop uniform across all routes and customers, or are there specific segments more affected?

Why it matters: Helps identify if the issue is systemic or localized. Expected answer: The drop is more pronounced in cross-country routes. Impact on approach: We'd prioritize analyzing long-distance route factors.

• Given the nature of intermodal transport, I'm curious about external factors. Have there been any significant weather events or infrastructure issues in key transport hubs?

Why it matters: External factors can significantly impact on-time performance. Expected answer: There have been no major weather disruptions. Impact on approach: We'd focus more on internal factors if external events are ruled out.

• Thinking about operational changes, has there been any shift in the mix of transportation modes used in the intermodal service?

Why it matters: Changes in mode mix can affect overall service reliability. Expected answer: The rail-to-truck ratio has remained consistent. Impact on approach: If confirmed, we'd look more closely at issues within each mode rather than mode mix.
