This has high potential!  Wink

Although they're going to need more than 50km range if they're going to be used on most of the network. Interesting though to see the competition between this, hydrogen, bi-mode, OHLE and possibly third-rail.

In my view, hydrogen is not a serious contender, it is inherently expensive, explosive, bulky to store, and challenging to handle at fuelling stations.

Neither in my view is any significant expansion of third rail a serious contender, for reasons already given.

That leaves bi-mode (25Kv and diesel)
Or 25Kv throughout
Or bi-mode (25Kv and battery)
As serious possibilities. A battery ONLY train seems unlikely due to lack of flexibility, and the need for large shore supplies for charging, rather than use of existing 25Kv infrastructure for charging.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

So is all that petrol you keep for friends in your shed!

I also think hydrogen seems an unlikely contender but several manufacturers, such as Toyota, are pursuing fuel cells as a serious power source for rail, road and I think marine too. So I guess we'll have to wait and see; the question is how long do we wait?

Tuesday had come down through Dundrum and Foster Avenue, brine-fresh from sea-travel, a corn-yellow sun-drench that called forth the bees at an incustomary hour to their bumbling.

The trains on this line are due for replacement (hopefully) within the next 10 years. It would seem logical to electrify at 25kv west of Basingstoke with dual voltage stock. As Reading to Basingstoke is likely to be electrified the addition of Southampton to Salisbury would give an electric route for the many container trains heading north without the complication of any work on the direct line through Winchester

If Redbridge to Basingstoke via Laverstock and Andover is to become the regular routeing for freight, would it not mean either a reversal at Redbridge or the addition of a western entrance to the freightliner terminal?

As far as I'm aware there is already a western entrance to the freightliner terminal,unless it has recently been removed.

Sorry, you are correct. For some reason I though it was eastbound only, but I've just looked on google maps and seen the layout quite clearly.  Embarrassed  Embarrassed
