Rail track,generator ballast wagons....
 

Weres the best place to see these wagons on the rail network??.....

If your in Wirral then I don't really know but I would suggest Whitemoor, Doncaster, Toton and Hoo. Although they predominately work at weekends, you do get the odd midweek one. A place that has a virtual quarry, i.e. Whitemoor is a place where you will see them all week being prepared for possessions at the weekend. Whitemoor departures and arrivals are easily viewed from the public highway. Most happen on a Saturday roughly between midday and midnight.

Cheers for the info!! ile have to go for look at weekends,yer im on the Wirral,but we only have electric emu over here:( never see any freight action,but my job takes me all over the country,so i see alot of freight then....:D
