I was just wondering why number 25 road was taken out of commission and, well, why is half of it still there and why did it spend so long under possession but still very much intact?

Too short for S-Stock...?

That's true. I just wonder why they took 25 road out when they did and left the other two roads. When they took it out the vast majority of trains on the Circle and H & C were still C stock and I was just wondering why 25 road went when it did and how it did.

Weren't the sidings decommissioned when the rebuild of Farringdon station began, for the extended Thameslink trains and for Crossrail.
There is a large shaft visible on Google Maps Streetview, on the former Network Rail trackbed to Moorgate, which is right next to siding 23. Keeping a short siding is probably a good idea, for keeping the connection to the running lines 'live' in case of future needs once the Farringdon works are finished.

Sidings are too short for S stock but have been used for track vehicles.

Restrictions on the use of 25 Road at Farringdon have existed for many years and long pre-date the S Stock. The problem arises because of its proximity to the running line. There was deemed to be insufficient clearance from the running line for staff to properly access a train stabled on 25 Road. Initially this restriction only applied to the fleet manager's staff preparing a train stabled on that road. Specifically they could not test the tripcock on a train stabled on that road and so the train which stabled there each night was a prepared train from Hammersmith Depot. This was the situation around 1999. Subsequently the restriction was extended to staff joining or leaving a train stabled on 25 road, and at that point the number of trains stabling at Farringdon each night was reduced from three to two with 25 road being the road left empty. I'm not sure when this change happened but it was certainly the case by mid 2002. 25 road could however still be used by a train laying over i.e. where the train operator who takes the train into the siding remains on the train and brings it back out of the sidings at a later time. With 25 road no longer in use for regular stabling it became a favourite location for hiding various engineering vehicles if they were required to be in that area for several nights running and it was quite common for this road to be under possession while these vehicles were stored there. Changes to staff access to Farringdon Sidings, probably prompted by the station's reconstruction, saw the erection of a staff halt at the east end of the sidings, adjacent to the westbound line, and 25 road was cut back to accommodate this. In effect this permanently changed its status to an engineering siding only. At about the time these changes were being made Farringdon Sidings were totally out of use for a time. Once restored however the other two roads continued to be used for overnight stabling until the introduction of S Stock meant this was no longer possible.
