| X 140 N11/B. Extract from 5.12.12. Re Series 2500 and 2600. X.140. X.383. Replying to your enquiry re the steps taken to overcome the vibration in the rear axle, we are making at the present, time, a rear axle having two sets of rear brakes and without the present central brake. It is possible we may be able to embody this improvement in series 2700 but this will depend on the results of the test. | ||
