The engine is of direct valve motion when the reverse lever is in the goahead
position , and of indirect motion when the lever in the back - up notch , the
reasons for this becoming apparent as the method for reversing the gear is
understood .

We have now completed the design of the Walschaert valve gear so far as it is
represented by Fig . 6 , except in supplying the mechanism by which the reverse
lever may shorten the cut - off and reverse the motion . In Fig . 6 the link - block
