- Most likely TT126 will be the very last TT class loco built.
- there are four more GT46Ace locos that have been purchased by GWA in the LN51 contract, these are already partially built at Cardiff
- 6 more GT46Ace units will be built, but have not been sold yet. After that its the end of the line for locomotive manufacturing at Cardiff, which will be used solely for rework and commissioning of WTP (waratah) and maintenance of locos.
Downer and EMD have been very quiet on exactly where their new locos will be built due to "commercial sensitivity", but I don't think it will be very hard to guess where this "off shore location" will be, since this all comes down to cost cutting...
