1. An accessory apparatus for a gas turbine engine having a first shaft that rotates when the gas turbine engine is energized, the apparatus comprising: at least one mount rail attached to the gas turbine engine and extending parallel to the first shaft of the gas turbine engine;a first accessory having a first mounting block, to mount the first accessory to the mount rail, and a first accessory shaft to power the first accessory; anda second accessory having a second mounting block, to mount the second accessory to the mount rail, and a second accessory shaft to power the second accessory;wherein the first accessory shaft and the second accessory shaft are operably coupled to the first shaft of the gas turbine engine and with each other;wherein the first accessory or the second accessory is mounted to the at least one mount rail via its mounting block and its corresponding accessory shaft is connected to the first shaft of the gas turbine engine; andwherein the first accessory shaft and the second accessory shaft are connected to each other;further comprising at least one clamp rail attached to the gas turbine engine and spaced from and extending parallel to the at least one mount rail, and a clamp nut slidably mounted to the at least one clamp rail and attached to the first accessory or the second accessory that does not have its individual accessory shaft connected to the first shaft of the gas turbine engine. 2. The accessory apparatus of claim 1, wherein the first accessory or the second accessory has a gear mechanism to drive the first accessory or the second accessory at a speed different than a rotational speed of the first shaft of the gas turbine engine. 3. The accessory apparatus of claim 1, further comprising a gear mechanism between the first accessory and the second accessory to drive the first accessory or the second accessory at a speed different than a rotational speed of the first shaft of the gas turbine engine. 4. The accessory apparatus of claim 1, further comprising a jacking lever mounted to the at least one clamp rail and configured to urge the first accessory or the second accessory away from the other of the first accessory or the second accessory for removal from the accessory apparatus. 5. The accessory apparatus of claim 1 wherein the first accessory and the second accessory include a starter, a fuel pump, a lubrication pump, a hydraulic pump, a permanent magnet alternator (PMA), a permanent magnet generator (PMG), a variable frequency generator (VFG), or a line replaceable unit. 6. An accessory apparatus for a gas turbine engine having a first shaft that rotates when the gas turbine engine is energized, the apparatus comprising: at least one mount rail attached to the gas turbine engine and extending parallel to the first shaft of the gas turbine engine;a first accessory having a first mounting block, to mount the first accessory to the mount rail and a first accessory shaft to power the first accessory; anda second accessory having a second mounting block, to mount the second accessory to the mount rail, and a second accessory shaft to power the second accessory;wherein the first accessory shaft and the second accessory shaft are operably coupled to the first shaft of the gas turbine engine and with each other;wherein the first accessory or the second accessory is mounted to the at least one mount rail via its mounting block and its corresponding accessory shaft is connected to the first shaft of the gas turbine engine; andwherein the first accessory shaft and the second accessory shaft are connected to each other;further comprising an oil scavenge circuit extending through the first accessory and the second accessory. 7. An accessory apparatus for a turbine engine having a first shaft that rotates when the turbine engine is energized, and having a gearbox to transfer rotational motion of the first shaft of the turbine engine to a second shaft, the apparatus comprising: at least one mount rail attached to the turbine engine and extending parallel to the second shaft; andat least two accessories, each having a mounting block to mount the respective accessory to the mount rail, and each having an individual accessory shaft to power the accessory;wherein the individual accessory shafts are disposed to be coaxial with the second shaft and with each other;wherein one of the at least two accessories is mounted to the at least one mount rail via its mounting block with its individual accessory shaft connected to the second shaft; andwherein the individual accessory shafts are connected to each other;further comprising at least one clamp rail attached to the turbine engine and spaced from and extending parallel to the at least one mount rail, and a clamp nut slidably mounted to the at least one clamp rail and attached to the one of the at least two accessories having its individual accessory shaft not connected to the second shaft. 8. The accessory apparatus of claim 7 wherein one of the at least two accessories has a gear mechanism to drive the one of the at least two accessories at a speed different than a rotational speed of the second shaft. 9. The accessory apparatus of claim 7, further comprising a gear mechanism between the at least two accessories to drive the one of the at least two accessories at a speed different than a rotational speed of the second shaft. 10. The accessory apparatus of claim 7, further comprising a jacking lever mounted to the at least one clamp rail and configured to urge one of the at least two accessories away from an adjacent one of the at least two accessories for removal from the accessory apparatus. 11. The accessory apparatus of claim 7, further comprising an oil scavenge circuit extending through the at least two accessories. 12. The accessory apparatus of claim 7 wherein the at least two accessories include a starter, a fuel pump, a lubrication pump, a hydraulic pump, a permanent magnet alternator (PMA), a permanent magnet generator (PMG), a variable frequency generator (VFG), or a line replaceable unit. 13. A method of assembling accessories with a turbine engine comprising: mounting a first accessory component to a mount rail secured to a gas turbine engine having a first shaft that rotates when the turbine engine is energized, and extending away from the turbine engine parallel to the first shaft of the gas turbine engine;connecting an accessory shaft in the first accessory component to the first shaft of the gas turbine engine;mounting a second accessory component to the mount rail and in engagement with the first accessory component; andconnecting an accessory shaft in the second accessory component to the accessory shaft in the first accessory component;further comprising aligning an oil scavenge circuit in each of the first and second accessory components to be in fluid communication. 14. The method of claim 13, further comprising securing the second accessory component to the first accessory component by a clamp nut attached to a clamp rail. 15. The method of claim 13, further comprising disposing a gear mechanism between the first and second accessory components to drive the one of the accessory components at a speed different than a rotational speed of the first shaft of the gas turbine engine. 16. The method of claim 13, further comprising: applying a jacking lever to the second accessory component;disengaging the second accessory component from the first accessory component using the jacking lever; andunmounting the second accessory component from the mount rail. 17. The method of claim 16, further comprising disconnecting the accessory shaft in the second accessory component from the accessory shaft in the first accessory component.
