What is the total length of railways in Brazilian states with GDP per capita above national average?

What is the total length of railways in Brazilian states with GDP per capita above national average?

Task conventions: This is a closed-catalog task. The complete original GeoBenchX source inventory is listed below; it describes available source types, not actual measurements. Do not supplement it with live data or claim numerical evidence from general knowledge. General knowledge may be used for definitions and explanation. Answer the original question as far as this information environment supports, accurately distinguishing observations, inference and uncertainty. This source-availability/control cohort supplies catalog metadata rather than the observation files and is reported separately from computational tasks.

Give a concise ordinary-language answer. No artificial count, result artifact, workflow or map is required when the answer does not warrant one. Do not invent observations or claim an analysis was run.
