Passengers as freight?

[Nortube]

I found the following freight path on OpenTrainTimes:
www.opentraintimes.com/schedule/H10843/2013-04-03

This is a regular freight train path from 05:35 Horsham Up Terminal Complex to 14:58 Horsham Up Terminal Complex, reversing at:
North Pole Junction, Herne Hill, London Bridge, Crystal Palace, London Bridge, West Croydon, Clapham Junction, Herne Hill, Epsom Downs and Sutton. Non-stopping stations in between.

It is interesting to note that it has "1st and Standard Class seats"

I assume this is a hiccup in the description, or have passengers been given an upgrade by fitting seats into the cattle cars?

If passengers were less animated they would be easier to handle and the railway would be much more efficient! Allowing them to think for themselves was an error made long ago, perhaps this is an attempt to begin to correct it!
