So if there is no exchange in the old Cathedral building do we have any ideas why my attenuation is so different to that of my neighbour? It is as if the cable I'm on goes much further to end up in the same place at each end..

It may well be that the cable goes a long way around to reach the same place

It could be you are on a cable that goes there and is then connected to one that goes back to the other exchange.
The MDF mentioned earlier is a Main Distribution Frame, which is what lines connect to at an exchange, so that MDF could be fed from the Barton exchange. Effectively as suggested by zyborg47.

The tie cable from Barton MDF (where the exchage is) to the Cathederal MDF (where your line comes in) adds 14dbs attenuation to your line.

OP's Attn. 70 -14 = 56 =^= Neighbour's Attn. QED! Unless, being an occasional "conspiracy theorist", the Anon arrived at the 14dB difference by the same calculation  .

True! Did strike me as I posted 
.: QED subject to not being a circular argument!
