Thank you for your question.
To our great regret in v1 of Telerik Reporting there is no way to bind report items to a deep object graph. The reason is that all properties of the top most object that are of complex types (type is not primitive, String, DataTime, Guid or byte) are discarded from the data processing engine. In your case this is the Location
property. As we skip this property there is no way how to access the StationName.
Please excuse us for the inconvenience. We logged the issue in our bug tracking system and will check how to overcome this flow for the next version.
