The LNER Encyclopedia

I am looking for details of the Gresley bogie as was used under the Mk1 catering vehicles from the fifties to the seventies..
Specifically; weight, wheelbase, wheel diameter...

Can anyone please help me?

Hi Tanya,

Not managed to get this information from anyone on the Yahoo! LNER, British Railways or BR Coaching Stock groups then...

The bogie was the 'heavy' type (due to the weight of the vehicle - see also Parkin p134), of 8' 6" wheelbase (as were the other types of bogie fitted to the BR Standard coaches), and having 3' 6" nominal wheel diameter.

Thanks. I don't suppose you know the weight and what the axle box bearings were made of, do you? I would put money on white metal but I am determined to get it right as I am writing an article for a magazine.
Does anyone have a side view photo of a Gresley bogie as used under a Mk1 vehicle that I could use in the article?

Best wishes

The 'heavy' type compound bolster bogie had a tare weight of 6 tons, with a maximum allowable load on the pivot of 18 tons. The axleboxes were the 'JJ' type, of cast steel (cf cast iron for the 'light' type) with Armstrong oilers, and the bearing liners were white metal with 80% tin content (cf 56% tin for the 'light' type). The bolster swing gear was carried on knife edges to reduce the number of wearing parts requiring lubrication and all the bogie types used helical springs of Timmis section (cannot find a description of these but it will either be the cross-sectional profile or a double-helix). A correction to my original reply, the wheel dia. was 3' 7".

Thanks ever so much for that.
So all the bolster springs, both bolsters, were helical and the primary suspension laminated?
And the wheels 3'7"?

Great stuff!

I will mention this forum in the article - fair does!

Is this the bogie you're talking about (not quite sure whether "sitting on" means that it was ever attached!)

There are two such mk1 catering vehicles on The Strathspey Railway. The bogies appear to be reused standard LNER heavy (can't remember if compound or double bolster) reused but with new top planks to suit the mk1 underframe.

Sawdust.
