The new Tesco refrigerated service will use class 88 presumably on electric power. If it needed to use diesel power on this train could it travel at a reasonable speed?

no, it has 4MW power maximum on electric, 0.7MW using diesel. The diesel is really only there for shunting

How are the refrigerated units powered? Are they diesel generators or can the loco's ETS supply be used?

They certainly all have their own generators but on ships they are plugged in to the main supply, not sure if that is the case on trains?

I have never seen any modern container flats with ETH jumpers - although I think a couple of scottish ones were converted a good while ago for an experimental service from Inverness to Thurso coupled to the passenger coaches when 37 hauled. It didn't last long. The cables were only jumpers to enable the ETH supply to get to the coaches as the flats were on the front of the train. I think they also had to through-pipe the vacuum brake supply as the flats were normally air-braked so a hybrid system evolved.

As Darandio above states refrigerated containers do have their own fridge units and fuel tanks. Presumably when they are loaded the fridge units are started and set to the required temperature for the goods inside.

In this weather the fridge units are probably put in reverse to keep the temperature up!

This is the snag with text versus the spoken word, lack of inflection etc.

This Bald Rick may read like a flippant point but goods do require temperature control. There are plenty of chilled items that say "don't freeze". If you have a temperature controlled container then by definition it does need to be able to warm the goods if the ambient temperature drops below the threshold for the goods.

A container carrying fresh goods from the Caribbean to a northern Russian port would quite possibly have a +30c on departure to say -20c on arrival temperature range. Frozen Bannas anyone. UK will still suffer below freezing conditions although not as extreme.

It's a long time since I worked in container haulage, but from memory - when a refrigerated container is taken from a storage yard to be loaded, the haulier also has to collect a 'genset' which is a fridge motor which attaches to the box. Container is then loaded as normal, box is dropped off at the port and plugged into a shore supply, and the genset returned to the storage yard. Then on board and at the arrival port the box is plugged in to shore power. The collecting haulier the other side does the same in reverse - collects a genset, then collects the box and puts the genset on, then returns the whole empty combo back to a storage yard.
I would expect boxes on board trains to have gensets attached, otherwise there would need to be shore power available both on the train and at both terminals, and sufficient gensets available at or near the destination rail terminal.

When I saw the thread title my first thoughts were which aisle are they in, and is there a Clubcard discount.... :D

I understood the design spec was that it could haul a full train on diesel just at lower speed; the starting traftive effort is the same on electric and diesel modes.

Sorry if l've missed the announcement's about this service but are the container's on a dedicated train or mixed in on other services?

Implies it's dedicated.

Not sure on north of the border or inner London, i guess this can be routed via the ECML (East Coast Main Line) if there are problems on the WCML (West ......)?
