Although the 90 is quite capable of hauling a heavy train the wet weather can and does cause problems. The gearing on them is not really suited to freight work which was one of the issues that was overcome with 86501. If 86501 is doing flat out 75mph that would be equivalent to an 86/6 doing 100. the same applies to the 90 its gearing means that a lot of power is put to the rail so pulling away in the wet will goes slipping. Although the 90's have sanding gear and it does work it is prone to getting blocked up. next time you get chance to look at a 90 look at its sanding gear and follow the pipework and you will see it has quite a long journey from box to rail. When driving a 90 in the wet it is a case of less haste more speed ie keep the amps in the yellow sector and gradually build the speed up it does take longer and sand will be needed but an element of driving experience is too.
