So, we are waiting ... with baited breath ....
Or did you realise you were, in fact, travelling 'down' the MML and have a sort of "Duke of York" moment as a result?
No, I was indeed travelling 'down' the MML, it's just that my seat was south-facing. The delay's been due to the fact that I've barely had a moment spare to collate my notes (as I'm staying at my partner's house in Coalville), but here they are!
Notes on the Up side (inc. Up fast, Down Slow & Up Slow):
Around 5 piles are in south of Bedford.
From Bedford to Oakley:
11 piles, then 2 boomed TTCs, a lone pile, 12 boomed TTCs with drop tubes fitted, 2 piles, then 18 more boomed & droppered TTCs.
From Oakley to Sharnbrook:
5 droppered TTCs, 8 piles, and another 4 droppered TTCs before the twin-track portal at the southern end of Radwell Viaduct.
Then 5 more droppered TTCs, 3 lone TTC masts, 7 boomed TTCs, 2 lone masts, 12 boomed TTCs, a lone mast, 5 boomed TTCs and then 11 piles up to Sharnbrook Jct.
From Sharnbrook to Irchester via the Fasts:
Up to the current end of the masts at Souldrop Bank, there are (in the Slows) 1 pile, a boomed TTC, a TTP, 3 boomed TTCs, a lone mast, 8 boomed TTCs, 2 lone masts, 4 boomed TTCs, a lone mast, a lone pile, 2 boomed TTCs and 2 bare masts.
Then, on the Up side of the fasts through Wymington: 22 piles, 7 single masts, and 57 piles before the Slows reconvene at Irchester.
From Irchester to Harrowden Jct:
3 bedanglied TTCs, 1 boomed TTC and 3 piles are in on the Slows around Irchester, then a large gap over both lines is present over Irthlingboro' Viadcut & thru Wellingborough station, with 1 pile around the Finedon Rd area. (Most masts here are up on the Down side).
From Harrowden Jct to Isham:
23 boomed TTCs, 1 pile and then 6 boomed TTCs were visible on the Up side.
From Isham to Kettering:
1 boomed TTC followed by 7 piles are up; a gap is present near the lorry park by the A14. After there, 7 piles are in until Kettering South Jct. 1 pile *might* be in between there and the station.
From Kettering to Glendon:
Nothing up until Kettering North Jct; from there, 11 piles, a lone mast, a boomed TTC, 2 boomless TTC masts, a pile, a mast, 7 boomed TTCs, 2 bedanglied TTCs, 1 boomed TTC, 3 bedanglied TTCs and 1 lone mast.
Results should be taken with a pinch of salt as it is quite hard to do all this on a moving train!
