This evil was partly remedied by elaborate arrangements for cooling
the injection water so that it could be repeatedly used, a device
costly and ineffective, and resulting in extravagant working, to say
nothing of the high charges made by the Paris company for supplying
water. To these drawbacks had to be added others of an even more
serious character. The engines first laid down were not economical,
and the compressors employed gave but a very inferior result; with
each extension of the plant, the efficiency of both engines and
compressors was increased, the most satisfactory, we believe, having
been those supplied by the Societe Cockerill, and one of which was
exhibited at the Paris exhibition in 1889. Still it was clearly
recognized that much better results were possible, results which
Professor Riedler claims have been attained and which will be embodied
in the new installation now in progress.
This central station is located on the left bank of the Seine, close
to the fortifications, opposite Vincennes and not far from the
terminal stations of the Orleans and the Paris, Lyons, and
Mediterranean Railways; the plan, Fig. 1, shows the position. The
works are separated from the river by the quay, over which a bridge
will be constructed for the transfer of coal from the landing stages
belonging to the company, into the works; as will be readily seen from
the plan, it would be quite easy to run junction lines to the two
adjacent railways, but with all the advantages given by water
carriage, it was considered unnecessary to incur the expense.
