Sure sounds like a 38 (the link works BTW), thanks for posting. Personally, I like 3830's whistle. I never liked 3813's while 3820's was very high pitched, like on the Belbin videos you downloaded before.
It certainly has a better sound to it than in the first few trial clips that I have watched, where the current sound is more close to how they generally sounded is in the initial blast. Would like to hear the whistle blown in a short blast, as per the old regulations that called for a short blast on passenger trains when ROW is given and the whistle sounded as acknowledgement and warning for people to move back from platform edge.
The whistle on the Facebook video sounds a bit different from the earlier trials - a bit higher perhaps?At least in theory, the boiler pressure was limited to 215 pounds per square inch pressure after the new inner firebox was installed in 1986.
The new firebox was designed to allow the original 245 pounds per square inch pressure. This might be expected to change the tone of the whistle.
Something different to listen to, a combo in a double headed tour train some years back, the standard whistle at first is from the Pcl, the second is of a 38cl, the whistle was/is unigue but was also fitted to one other 38cl before withdrawal and fitted to this one
I don't know if the link will work or not, so far its not, seems dropbox has changed a lot.
Thanks for the heads up Studdo. That whistle on the Belbin video, I gather you are talking of 10 at Hawkesbury river, is very much the standard of how they all generally sounded, also the shortness of that whistle is the typical ROW whistle blow. For me whenever I heard a whistle like that I immediately looked for a 38cl. I have been to China on several trips to capture the last of Chinese steam, of interest is their steamers had the same style and chime whistle as the 38's and they were on the JF, JS, SY & QJ, the first 3 classes also had both two single phase, with some having the cross compounds, with the QJ's having a large cross compound with a small mechanical lubricator on it, which was an interesting sound, the other 3 classes no matter them being single of cross compound types, sounded the same as the 27, 30Ts and 36cl.
As I reflect on the 38cl that I have both worked on and have captured the sounds of them including the whistles, what I have found is there are few that are very much the same tones. although in the main the initial sound will very much depend on whether the whistle is opened/operated by the drivers side air depressing valve or by the whistle chord. I found that most that had the chord opened tended to have a trail off and with less steam going through the whistle making for a lower sound at the end. I did firemans trials on 3809 and on the few occasions as a fireman and had to blow the whistle it actually had me looking for another engine nearby as the end sound was totally different.
The other aspect with the 38 and from what big engine drivers would say was water build up in the pipelines. The 57cl had a depression handle on both the drivers & firemans side, drivers usually wanted the firemans side turned off with the gate valve as the lines always had water in them and if one side was operated there would be water spray up from the valve, sometime very dirty, they got the fireman to use the chord.
The whistle in the clip is very much different to the normal 38cl, and when one heard it out on the road it sounded very unique indeed. Loved it.
