I'm wondering if this is sarcasm. If not, then, yes, the country was dotted with huge arrays of withdrawn and condemned stuff that could be there for years. Micheldever, Hither Green up yard, Crewe, Stonebridge Park and so on. In the immediate case of the 769s, they are not being got off the overall rail sector's books, only transferred to another area of it for accounting reasons when perhaps they could be used for testing purposes rather than employing desperately-needed service stock for that testing (assuming they are not so dire that they would instantly fail and snarl up the testing route that is).
