Nabil N. Ghaly, chief signal engineer in the department of capital program management at New York City Transit, said that it was a gradual implementation of technology. Dr. Ghaly, an electrical engineer, said the new system would increase by nearly 20 percent the number of trains that can be operated at once on a line; at the height of the commuter rush, for example, 33 trains an hour might pass through a station, compared with today's 28. Dr. Ghaly said that the next line projected for modernization is the No. 7. Design for a new signaling system on that line is to be completed this fall, with a contract to be awarded next year.
