I beginning to wonder if the 769s will ever run in service. Perhaps with hindsight bolting an engine, alternator fuel tanks etc under a 30 year old steel, presumably corroded, coach was not such a good idea.

corrosion found would off course be repaired
adding about 8 tonnes to a 32tonne coach [40t]still loads it 16.5% less than a 48tonne motor coach
