With regard to the dynamo, we are arranging to carry out tests as soon as possible, to ascertain what effect the addition of chokes in the leads has on the control brush setting etc. This is important because the dynamos we are now supplying for the tank engines are set to their maximum value for safe heating, which is slightly in excess of normal setting we give them for the cars.
