As regards the line from Paris to St. Germain via Pecq,we may mention that from the date of the suppression ofthe atmospheric system of working up to 1886. the trainswere hauled from Paris to Pecq by four-coupled engines,while the part of the train destined for St. Germain wasthen taken on from Pecq by powerful six-coupled tank en-gines with wheels 4 ft. 3 in. in diameter. This change ofengines at Pecq occupied five minutes, and moreover ledto frequent delays, and this, together with other consider-ations—among them the desirability of running sometrains between the terminal stations without intermediatestops—led to the construction of the engines now illus-trated, suitable for working trains over the w
