This might have been posted in another thread or section for another station but if so I could not quickly find it.
I noticed on Friday the TBTC loop cables in the 4 ft between platform faces at Finchley Road are now raised on little masts about 10 cm high, only still at sleeper level at the loop crossovers.
Those masts have appeared only with the last 2 weeks : I usually use Finchley Road 2-4 times per week for a NB Met -> NB Jubilee (for West Hampstead Thameslink) home bound commute but working a bit different and TL in a shambles several evenings the past couple of weeks, Friday being the first time since then, so did not notice these until then.

Also noticed this, maybe its a reliability measure you know with trains not picking up codes etc

It has been raised as an experiment to reduce interference between TBTC and the traction cables that run under the track at that location. Something similar has been successfully done at Waterloo. These are the only two locations on the line that are expected to need this fix. Everywhere else on the line the TBTC track to train comms has now been brought to a reliable level.

And now I see on the NB road the loop cable is back on the sleepers, while on the SB road there is just one section of little masts at the north end. Well OK I did not walk the full length of the platforms but thats near enough what I could see today from the north end.
Experiment not a success then ?

No not successful but the problem it was intending to solve has largely disappeared so unlikely to need further experiments there.

Yep, and it works, so expect it to stay raised up, atleast for the duration of the Olympics.

The reason for the doubt is because its a trip hazard, and may cause issues if having to de-train for the passengers to walk down the track, and for staff working in the area.
As it seems to fix an reliability issue, I can't see it ever being lowered again, but that still needs agreement - it is officially still a trial because of the hazard it introduces, and will have to be removed after the Olympics as it currently stands.
