The Network Rail report also states that Meldon Viaduct would need replacing. This again depends on what option may be used to cross it,  or build a new viaduct. I have been told that the Meldon Viaduct company think it could be repaired for around 15-20million for a single line of track. This is much cheaper than a new viaduct. This could make a significant difference to costs.

The reports figures also include the inevitable 66% contingency on top, or optimism bias as you state Grahame

Every re-instatement is going to have its special case expensive sections.    Option 4 (alternative route B) from the Network Rail report quotes 470 million for a line from Newton Abbot to Exeter via Heathfield and Christow, which is about 5 miles of just operational line  and 15 miles of reinstatement.  At 20 million per mile (re-instated) and 14 million per mile (upgraded) that comes in at 370 million - you need to go up to figures like 25 million per mile for re-instatement and 19 million per mile for upgrade to reach the NR quoted 470 million.

Agreed I'm including contingency.  Also noting the report is dated September 2014.   Have prices gone up since then, or would improving techniques allow savings to be made?
