I hadnít heard about any gearing change but with only one motor per truck, the weight was spread out making it easier on the manhattan el structures. Even with the, The composites were still too heavy for regular service on the 6 and 9 Av els except for 155 St station itself which had been reenforced for the NYCRR trains which terminated there years earlier. As operated on the Manhattan els, the Composites were all motors with no trailers which presented no problem, however when the Composite trucks were installed on the Qs with trailers in the consist, their performance was worse that the Composites. I didnít realize that the Qs went to the Fkln shuttle around the same time they were being prepared for service on Myrtle, but it does make sense that they would operate poorly going upgrade most of the way from PPk to Fkln. An upgrade trip on Myrtle between Washington Av and Bway was equally demanding on the Qs as well.
