This likely comes down to how it accessed the bus schedules (i.e. web search tool) and not intelligence.

You need to add the actual bus schedule to context somehow (research agent, custom tool or just dump in prompt) and even the simpler modern models will be able to do the planning.

Tool usage competency is part of overall intelligence. If the model can't get the information it needs, it must clarify that in the response.

		This isn't tool usage competency, it's tool quality and/or luck. Regular web search is not good for grounding if you want accurate results. You can ask the model to make a tool for getting bus schedules and then use it only then you are comparing apples to apples in this case.
