I think any kind of merchandise light enough to be lifted by a man would be prone to be stolen if shipped in a gondola.
I think any kind of sewer pipe would have a relatively thick wall making lengths of the larger sizes (say 10 or 12 inches in diameter and above) pretty difficult for a man to lift, particularly over the side of a typical gon.
I've heard that cast iron pipes were shipped in P&LE and PYMcY (Al Westerfield calls this RR P mickey)gons. How about PRR gons?
Where were clay sewer pipes made?
Did these pipes have to be blocked? I would think that cast iron pipes would be robust enough to avoid damage without blocking.
A few years ago the neighborhood when I live had new storm sewers installed. A man can crawl through the concrete sewer pipes. I live above the east extension of the Grand Coulie damn.
