Some interesting information in the newly published franchise document regarding the use of 68s by TPE is that the number of locomotives could be increased up to 18, and that once electrification is completed some or all could be replaced by 88s, if they are available. Although the maximum speed of the 88 as specified for mixed traffic is 160 kmh (100 mph) the design speed for passenger use only is 200 kmh (125 mph). This could mean that if there is a requirement for more 68s in the future, then this could be achieved by building more 88s, perhaps geared for higher speed also. All depends on how far away the electrification is in reality.
On the 68 front in Valencia 68029 is now looking complete in plain blue livery and 68030 was out on the test track today, also in plain blue but far from complete in other respects.
