The Anonymous Widower

Weight And Dimensions Of A Class 345 Train

If you look at the Wikipedia entry for a Class 345 train, dimensions and weight are rather sketchy.

• Train length is given as 205 metres.
• Train width is given as 2780 milli-metres, with a note saying a citation is needed.
• Train weight is given as less than 350 tonnes.

These would be for a full nine-car train.

This picture shows the identification plate on the end of an MS1 car in the current seven-car train.

These figures can be read.

• MS1 car weight is given as 36.47 tonnes
• MS1 car length is given as 22.50 metres
• MS1 car with is given as 2.78 metres.
• MS1 car seats are given as 52
• Train maximum speed is given as 90 mph
• Train weight is given as 255.46 tonnes.
• Train length is given as 159.74 metres.
• Train width is given as 2.78 metres.
• Train seats are given as 350.

Note.

1. It’s all clearly there in white-on-black.
2. The Wikipedia figure for car width is correct.
3. The Wikipedia figure for maximum speed is correct.
4. I was also able to read the plate on a PMS car, which gave a weight of 37.12 tonnes.

So can I deduce the figures for a full nine-car train, which have two extra cars.

I did find this snippet on the Internet which gives the formation of the nine-car trains.

When operating as nine-car trains, the Class 345 trains will have two Driving Motor Standard Opens (DMSO), two Pantograph Motor Standard Opens (PMSO), four Motor Standard Opens (MSO) and one Trailer Standard Open (TSO). They will be formed as DMSO+PMSO+MSO+MSO+TSO+MSO+MSO+PMSO+DMSO.

The snippet has a date of August 13th, 2016, so it could be out of date.

But is compares well with the current seven-car trains which appear to have a formation something like.

• Driver-motor car
• Pantograph car
• Motor car
• Trailer car
• Motor car
• Pantograph car
• Driver-motor car

So to convert from a seven to a nine-car train two motor cars are added.

Nine-Car Train Length

This would appear to be 159.74 + 22.50 +22.50 = 204.74 metres.

That would agree with Wikipedia’s figure of 205 metres.

Nine-Car Train Weight

This would appear to be 255.46 +36.47 + 36.47 = 328.40 tonnes.

That would agree with Wikipedia’s figure of less than 350 tonnes.

Details Of The Driver Motor Car

Once I have these details, I’ll have everything I need.
