The Meigs Railway
"Quite a large party of scientific and financial gentlemen from Boston and elsewhere visited the Meigs elevated R.R. works on Tuesday last to see the practical working of the system, which, from present indications, seems likely to be adopted as the means of rapid transit in this vicinity. Capt. Meigs gave the visitors every possible facility and from what could be learned from individual expression of opinion the result was highly satisfactory."
