companies who use rail in their supply chain
Many companies do, but not directly
In general you need to look at your end supplier, at some point the goods may have travelled by rail, but not in all cases
Retailers tend to use an intermediary, who have all the resources; containers, HGVs, etc
As above, Tesco are the obvious retailer, now using DBS
Safeway used to, through Malcolm Logistic, now transferred to Morrisons
Asda also took advantage of this service
However, you would only benefit from this if you were a customer of those stores (Ullapool, Thurso, Wick, Aberdeen)
M&S use Freightliner, but not directly, through GIST
Power station operators use rail almost exclusively, over road transport
The construction industry has a long way to go
However, London Concrete and Hanson Aggregates are two main companies that have expanded their facilities
Even when you travel by plane, the fuel used may have arrived by rail rather than road
This would apply to flights from Prestwick
