Possy92 Posted January 31, 2021 Share Posted January 31, 2021 Hi all, currently building a parkside pc21 (16 T mineral wagon) I'm looking at the transfers and see the number, the v for the door, and white stripe, but I don't know what the 7-15, 7-8 7-9 mean? (I'm sure I've seen these on other wagons) Is it empty and fully loaded weight? What are these numbers for, how do you determine what goes on your wagon? pic of the offending transfers, circled in red! Thank you for your time! 1 Link to post Share on other sites More sharing options...
brossard Posted January 31, 2021 Share Posted January 31, 2021 They are Tare markings and represent the weight of wagon unloaded. Used for assessing charges for carrying the actual load. Loaded weight less Tare. For the wagon in question, I think any can be used since wagons would always have a slightly different weight due to variations in manufacture. They mean Tons and Hundredweight. There a lot of pics of this wagon around so check those. John 2 1 Link to post Share on other sites More sharing options...

pete_mcfarlane Posted January 31, 2021 Share Posted January 31, 2021 The \ / symbol shows that the wagon had bottom doors. Not all of them had these and I don't think they were common on diagram 1/108 wagons. If you look on this site there are loads of photos of BR mineral wagons which should help: https://paulbartlett.zenfolio.com/brmineral 1 1 Link to post Share on other sites More sharing options...
brossard Posted January 31, 2021 Share Posted January 31, 2021 (edited) Agree Pete, Dia 1/108 did not have bottom doors (at least the one I built didn't). These wagons had brakes on one side with Morton clutch for the non braked side. LMS did the 1/108 precursor and it had bottom doors. This wagon had independent brakes on both sides.

Trog Posted January 31, 2021 Share Posted January 31, 2021 7.15 Empty weight of 7 tons and 15cwt. An older wagon might be marked 7.15.2 Empty weight of 7 tons, 15cwt and 2 quarters of a cwt. So the second figure should be in the range 0 to 19 and the third should be from 0 to 3. cwt is hundred weight for the youngsters amongst us 112 lbs. 1 1 Link to post Share on other sites More sharing options...

Many many years ago, when I were a lad at school, it was reckoned that a thrupenny bit dropped of the Empire State Building had an effective mass of 1lb when it reached street level. It was, amongst many other things I learned at school, a useless piece of information, as when I actually made it to the top of the aforementioned building, I couldn't find an American with a thrupenny bit in their pocket, mind you, it was in the 1980's.

Agreed and accepting there can be a large range even for similar wagons, is there a rough rule of thumb for how much fitted brake gear adds to the weight of a 9 or 10 foot wagon? I'm thinking where fairly comparable, say a gwr fitted v unfitted morton. The cylinder would be a heavy lump I'd have thought, plus extra pipes, tie bars etc. The difference for early 16t minerals would probably be quite a bit as you are comparing one sided mortons v clasp fitted. The weight markings are less obvious in the later liveries so not always easy to see in Paul Bartlett's generally indispensable photos. I have loads of spare weight markings but am usually guessing which ones are most appropriate. Edited October 22, 2021 by Hal Nail Link to post Share on other sites More sharing options...
Nick G Posted May 3, 2022 Share Posted May 3, 2022 I was going to start a thread to ask a question about a marking on 16t minerals then found this thread. When looking at pictures of 16 tonnes some have a white arrow pointing down and a 'star' symbol on the side doors what do these mean please? Link to post Share on other sites More sharing options...

White arrow pointing down is the indication of the "change over" lever for loaded/empty. (May have an additional brake cylinder for loaded.) The star, in white for air, yellow for vacuum, denotes location of the "brake release cord". Edited May 3, 2022 by 33C Missing letter. 1 1 Link to post Share on other sites More sharing options...
Cwmtwrch Posted May 3, 2022 Share Posted May 3, 2022 VB 16 ton minerals [which this picture shows] did indeed have two brake cylinders. The star was always white on VB wagons, and coaches I think, at least before air brakes appeared on BR. 1 1 Link to post Share on other sites More sharing options...
