NER Class R (LNER D20) Boiler Pressure & Livery
Posted: Thu Jun 27, 2019 9:57 pm
I'm having a bit of trouble regarding the D20, the first paragraph on the D20's page (Here) states they were built with a maximum working boiler pressure of 200lb/in², the boiler is also listed as having a pressure of 160lb/in², I assume this was when the locomotives were fitted with superheaters (As per NER practice), but my Ian Allan ABCs state the pressure was 175lb/in² by 1944.
My question is, when did this happen? I'm assuming prior to 1923, as the R1s (D21) also had their pressure reduced to 160lb/in² (from 225lb/in²) when superheated, and upped again to 175lb/in² prior to grouping.
Liveries, part the first:The preserved D17, as with the D20s, is dual braked; on the tender the air standpipe is painted white and the vac one is painted red (I know that NER carriages had a red V and/or a white W to show with what brake system they were fitted, vacuum, westinghouse, or both), did dual-braked locos also have this colour coding?
Part the second: In 1900, two B13s had gold lining (gold leaf?) added to them for hauling a Royal Train, the NER Record Vol.3 Page 122 states that afterwards this livery was also applied to other classes of locomotive ("Gold lining was subsequently adopted for all other principal classes of locomotives, and for those tank engines reserved for hauling the NER officers' saloons.").
I assume the D20 was included in this, and that at some point the Gold was replaced with "straw yellow", but was this livery retained until 1923?
Thanks in advancve for any help!
