Some railway stats found

Mi and I have been looking for statistics of agricultural commodities carried by rail, just got a bit lucky. I checked the 19th Century House of Commons Parliamentary Papers under 'railway returns'. And found very detailed statistics for all sorts of carriage. Cattle are lumped in with other goods etc until about 1860. Then we get detailed record by head of cattle, pigs, etc. We now have to work out how much effort is required to extract the data and whether the end result will be worthwhile.
