dave_long Posted January 1, 2012 Share Posted January 1, 2012 Hey all, I'm looking for some help I'm trying to model a rake of ICI Mond Division TT051J chlorine tanks. Or this set to be precise http://petertandy.co...eygreen_t48.jpg & http://petertandy.co..._T48_SmethW.jpg I'm pretty well off for most details ie converting Baccy TTAs, but what I'm interested in is the tank hatch on the top centre. I've looked in a few places for a replacement part but I think that its not been catered for after market. What I was thinking that I may be able to use something from older tank wagons ie a 14T tanks or old oil tanks. Either that or I have thought about maybe getting something built from 3d cad designs ie Shapeways, but then I have no real dimensions although an approximation could be made. Paul b's gallery : http://paulbartlett....a53c5#h23e2a104 14T chemical tanker 00 gauge: http://www.rickocraf...line/37-682.jpg looks similar... What do you guys think?

Pugsley Posted January 2, 2012 Share Posted January 2, 2012 I've got a good, side-on, photo of these wagons somewhere. Give me a day or two and I should be able to give you a rough idea of the dimensions of the top cover. Link to post Share on other sites More sharing options...
dave_long Posted January 2, 2012 Author Share Posted January 2, 2012 Thanks Pugsley any photos would be great, I found a Colin Craig drawings set for the TT051J in Modelling the British rail era book (Santona). I may have confused the issue with posting a link to the 14t tank, but that was posted to show the top hatch to see if it could be used. I was hoping to use a Baccy Fuel/oil TTA as a base but need to check the tank diameters, as I'm not sure if they are the same. Regards Link to post Share on other sites More sharing options...
Pugsley Posted January 2, 2012 Share Posted January 2, 2012 The tank diameters won't be the same - the oil tanks had larger barrels and the Barrowmore MRG digram book will have the TT051J in it, which might give the barrel diameter. I say might, as quite often the width of the wagon was quoted over the ladders, without the barrel diameter being specified. If it helps, 45T monobloc wagons are generally 7'0 over the outsides of the solebars. The Bachmann chassis should be a good starting point, you'll just need to build everything above the solebar.

dave_long Posted January 2, 2012 Author Share Posted January 2, 2012 Thanks Pugsley. The barrowmore books have the TT051A-D but not J. However i'm hoping that Colin Craigs drawings will help as they are to scale and as trustworthy as I think I'll ever get. The books state : 1981 over the journals; 2490 overall width.

Pugsley Posted January 3, 2012 Share Posted January 3, 2012 Yes, you can rely on Colin's drawings, so you don't really need my help with the top cover and the photo I have is of the earlier tanks (51421) The diagram you want in the Barrowmore set is TT051C, looking at the wagon numbers on the diagram. According to the Metro book, TT051J were numbered between 51649 and51719 in 1990, and the TT051C diagram covers up to 51723. HTH Link to post Share on other sites More sharing options...

hmrspaul Posted January 3, 2012 Share Posted January 3, 2012 Yes, you can rely on Colin's drawings, so you don't really need my help with the top cover and the photo I have is of the earlier tanks (51421) The diagram you want in the Barrowmore set is TT051C, looking at the wagon numbers on the diagram. According to the Metro book, TT051J were numbered between 51649 and51741, and the TT051C diagram covers up to 51723. HTH The diagrams were for the same wagons, the difference was that 51C had double link suspension http://PaulBartlett....netta/e2dd31e37 , and 51J was issued for when they were provided with FAT 28 suspension http://PaulBartlett....netta/e3841a320 . I cannot see where these higher numbers come from. The diagram book index gives TT051C as 51649 - 677, 679 - 723. TT051J gives 51649 - 677, 679, 680, 682 - 720. The small difference is number series reflects, I believe, that a few were withdrawn before the suspension was altered. TRL 51724 - 763 were diag. TT065A lagged class B tank wagons built Chas Roberts in 1967 (I have at least 7 photos of these, but they are not in the Metro Marshall edition I have). The drawings on the diagrams are different, apparently reflecting that many had plain end caps - the drawing of 51C reflects this http://PaulBartlett....netta/e3f694ec8 (a 51J) and some as on drawing 51J had small protrusions on the centre of the cap as http://PaulBartlett....netta/e2f601562 (a 51C). What neither of the diagrams reflect is the addition of buffer override protection as http://PaulBartlett....netta/e2407ee15 Both diagrams are very basic with minimal dimensions.

dave_long Posted January 3, 2012 Author Share Posted January 3, 2012 Thanks for the info Paul. The initial plan is for just four models, to model the formation in the Peter Tandy links in op. I believe from looking at them under a high zoom that they are the Tiger labelled tanks, and although I cant tell much more from the photos, I decided it best to go for the 51J diagram. So there are plenty of numbers to choose from to make a small rake. I'll take some measurements from Colins diagram and see what he has drawn and see what I need to create the tank body. Thanks for the help Dave Link to post Share on other sites More sharing options...
Southernman46 Posted January 3, 2012 Share Posted January 3, 2012 I hope you are all suggesting these to Realtrack as their next RTR wagon offering ! Link to post Share on other sites More sharing options...
Pugsley Posted January 3, 2012 Share Posted January 3, 2012 I cannot see where these higher numbers come from. Looking at the Metro book now that I'm more awake, I can't see either. I'm going to put it down as an error made when I should have been asleep and amend the original post! The 1990 Metro book goes from TRL51649 to 51719, with a few gaps in between.
