A few points about the Crostis. The secondary "Boiler" was removed at rebuilding. Not all ended up on the Wirral (Birkenhead) - some went to Speke Jct (Liverpool). Although it seems generally agreed that an ex-crosti was 8F, my memory tells me that "9F" was displayed on the cabside.
An interesting measure of power was the number of 88-ton gross iron ore wagons that various types were allowed on the Biston Dock - Shotton steelworks trains. 8Fs, ex-crosti "9Fs", English Electric Type 4s (Class 40) and pairs of Sulzer Type 2s (Class 24) were allowed 10 wagons and 9Fs and Brush Type 4s (Class 47) were allowed 11. At least once a 9F took 13 - a gross load of around 1160 tons. These wagons were unbraked so half the battle was to stop them once over the summit.
