Claim 8

The mobile track surfacing apparatus of claim 1, further comprising an adjustment means operatively connected to the means for indicating the desired superelevation to set this means to a selected superelevation.

Claim 9

independent automatic means for adjusting the vertical distance of each of the transmitters from the associated rail independently of each other, each automatic means including a. a drive motor for effectuating the vertical distance adjustment, b. a control means operatively connected to the drive motor for actuating the motor in response thereto, c. a means indicating the desired superelevation of the track, the control means being responsive to the superelevation surveying means and being operatively connected to the desired superelevation indicating means whereby the drive motor automatically adjusts the vertical distance of the transmitter associated therewith in response to the desired superelevation and automatically takes into account the difference between the surveyed and desired superelevation;

Claim 10

independent automatic means for adjusting the vertical distance of each of the transmitters from the associated rail independently of each other, each automatic means including a. a drive motor for effectuating the vertical distance adjustment, b. a control means operatively connected to the drive motor for actuating the motor in response thereto, c. a means indicating the desired superelevation of the track, the control means being responsive to the superelevation surveying means and being operatively connected to the desired superelevation indicating means whereby the drive motor automatically adjusts the vertical distance of the transmitter associated therewith in response to the desired superelevation and automatically takes into account the difference between the surveyed and desired superelevation;

Claim 11
