TfW Class 197's

[Wagonmaster]

I'm trying to build a model of TfW's Class 197 dmu. However, trying to find out some details of these units is proving difficult. I'm hoping that some of you on RMWeb might know, or point me in the right direction.

 

The first problem is wheel diameter. They look quite small to me abd I wondered if anyone knew what the wheel diameter is? The bogie wheelbase appears to be 7ft. 6in. If anyone has built one, what did you use?

 

The second main problem is car numbers. I have found lists of unit numbers, but not individual car numbers. With the units I've seen, they seem to have the car numbers at the inner ends and a long number underneath, which I'm  guessing is the European number system? The numbers also appear to be a dark grey rather thzn black. Is that correct?

 

I think I have the paint shades right with Goosewing Grey for the main body colour and Traffic Red.

 

Any help gratefully appreciated.

Sorry I don't know the answer to any of those but did take a slightly iffy picture the other week (while waiting for the level crossing).

This link for the very similar 195s may be useful. It contains some outline drawings and gives bogie wheelbase as 2.25m

Despite having done a lot of work on the yaw damper bracket issues on these in a previous job, I'm afraid I no longer have access to  the technical data and I can't remember the wheel diameter range.

Thanks for your reply and the info. I should really get the latest Platform 5 edition!

Thanks for your reply. As it happens, I did come across that document. 2.25m is about 7ft. 5in., so not too far out!

 

Pity it didn't show wheel diameter, but I'm guessing they might be 870mm? Would that sound about right?

I'm pretty sure they're smaller than 870mm. Turbostars etc are 840mm new, and I think these are smaller than that.

Let me ask Northern maintenance control and see if he knows.

Thank you, that's very kind of you. My second guess would be 760mm, but they're always going too fast for me to measure!

Just a few recent shots of what some local enthusiasts refer to as 'Marvins' ( and no,  I don't know why ).

.

Good luck with your modelling them.

Marvin the Paranoid Android?

I would assume it’s a reference to the paranoid android from the original hitchhikers guide to the galaxy. There is a passing resemblance.

As soon as a 197 pulls into your station, you feel very depressed.
