I'm sure I recall a change of specification regarding the length of units they operate being made by the regulator to their renewed track access application, which meant they really had no choice but to take the 180s. Does anyone else remember this?
Fingers crossed they can soldier on for the next 12/18 months without it damaging their business too badly.
On the right lines but not quite. To get your length of term in the track access contract, you have to propose and sign up to certain investment conditions. HT proposed taking on the 180 units and doing a certain amount of refurb. work as part of the track access application. The ORR made that an enforceable condition and if it wasn't done, the TAC would revert to being a shorter one.
When (as an OAO) you apply for a TAA, the ORR examine your business plan in some detail. The time it takes to recover costs and what rate of return you need to seek has a strong bearing on the length of term they grant you in their determination.
The current difficulties are as a result of 110 being out for the fuel tank (and other) repairs and the need to stop other units as they fall due for mileage exams. 180 units usually have a fair amount of repairs arising so each B exam takes a few days, especially if it results in an engine needing to be swapped out. The repair of 110 is going well and it should be back in traffic next month. Until then GC are helping HT out, when they can.
