APT-E or APT-P? Ian

I must admit I'm impressed with: Ian

Yep. As it says in the original post "... I suppose this has been done for small (low single digit) fleets of obscure / speciality rolling stock. But how about 'mainstream' ## rolling stock?" Ian

Some more for the 'list' started by @25kV: BT38 / BT38b - Used on Class 153 & 155s (Modern Locomotives Illustrated Feb-2015 / Mar-2015). BT52 - Class 323 & Class 465 (Alsthom built) (Modern Locomotives Illustrated Feb-2017 / Mar-2017 & Dec-2017 / Jan-2018). T3-7 - Class 319 & 321 (Modern Locomotives Illustrated Dec-2017 / Jan-2018). T3-17 - Used on Class 165 Networker Turbos & Class 166 Networker Expresses (Modern Locomotives Illustrated Dec-2015 / Jan-2016). T3-23 - Used on Class 168 Clubmans (Modern Locomotives Illustrated Dec-2015 / Jan-2016). T3-23c - Used on Class 170 Turbostars (Modern Locomotives Illustrated Dec-2015 / Jan-2016). Ian

Agreed. Here is an extract from the July 1975 issue of Modern Railway "Production Mk III coaches are equipped with the BT10 bogie, designed for high-speed running with minimum maintenance. Changes from the prototype BT5 version (described and illustrated in the June 1972 issue of Modem Railways) are minimal." Plus: BT8 - Used on Class 312/0, 312/1 & 312/2 BDTSOL, TSO & DTCOL coaches (Modern Locomotives Illustrated Dec-2017 / Jan-2018 & Nov-2018 / Dec-2018 issues). Ian

Platform Building Finally in Place on the Platform Finally, the Platform Building is correctly situated (embedded 2mm) on the platform, with the Bay Platform shortened to suit: The next logical step is to complete the surface 'textures' for the Platform. That will enable me to get back to the Overbridge support columns to be installed 'in' the Platform surface, where I was over 3-weeks ago! Ian

@Dunalastair recently commented (flippantly, I'm sure) in @young37215 topic "West Highland Line V4, a 1980's West Highland Line layout" that with 11 Class 37s on his layout, that left only 298 more to go (to complete the 309 built). Which begs the question, has anyone modelled a 'complete fleet' of locos (or anything else, for that matter) on their layout? Yes, I suppose this has been done for small (low single digit) fleets of obscure / speciality rolling stock. But how about 'mainstream' ## rolling stock? I think @25kV might have done the entire Class APT-P fleet? ## - I'm leaving this deliberately vague Ian

I 'wish' you were right, as this is becoming a hard one to crack. However, as I said yesterday: I found a reference to BT15 in The Railway Observer from 1979 "BT15: 11032 (Clouth primary suspension)." So that solves that one for you. Clouth do 'rubber' suspensions, and my original photo shows coil springs. Ian

I can confirm that the photo was taken on 6th September 1981 at Doncaster station. That's a mighty effort at trailer bogie listing. Very impressive. You can add BT10b to the list as Modern Railways January 1993 states "InterCity has received tenders from two firms offering a BT 10-upgrade package along these lines. It was hoped to equip a complete rake of coaches with these modified BT10b bogies, but budgetary constraints could limit the evaluation set to half a rake." I found a reference to BT15 in The Railway Observer from 1979 "BT15: 11032 (Clouth primary suspension)." So that solves that one for you. We'll get there eventually ... Ian

Paul, Any reason to use XLR sockets / plugs? I thought they were expensive and, of course, limit you to a number of connections (unless you increase the number of XLR connections). Just curious ... Ian

Am interested in 'getting to the bottom' of what that bogie is under E42224, so actually any information would be very much appreciated. If you are aware of 'mods' that resemble the bogie of E42224 that'd be a good place to start. I'm guessing 'my' bogie is some sort of development bogie/mule, so maybe you have information of similar bogies that pre-date and post-date it? If you could also help with the 'publications of the period', I can check back with my library of scanned magazines. Some key words would help. Ian

Sounds promising ... do tell more. Ian

The T4 bogie seems to have been proposed for the Mk4 coaches in ~1987. My photo is from 1981, 6-years earlier. So it is some kind of test 'mule' for the eventual T4? Ian

This is really annoying ... I can't find any other photos / details of that bogie under Mk3 E42224. I found that the BR International Train used BT10 and T4 bogies, but neither is that bogie under E42224. What's more annoying is that I don't think I even noticed the bogie differences when I took the photo! My notes just record the coach numbers. Here's hoping someone can provide the missing info. Ian

I use clear PVA to glue all my inkjet 'print at home' textured papers. Just make sure you have one of these to properly adhere the paper: For the paper, I've found that 100gsm is a good compromise. It's thick enough to 'feel good', and the glue doesn't penetrate through to the ink so long as you use it sparingly (and when it does, it does look like weathering!). I did originally use 'pritt sticks' (or similar equivalent), but I found them to be messy. When you go around the perimeter of anything, the glue inevitably ends up on your desk / work surface. With PVA I just use a small paint brush to apply the glue on small areas. For larger areas I spread it with an old toothbrush. For the roof, it's well worth installing each row to tiles individually, overlapping as you go. It look so much better. Here's how I do mine: And installed on the building: Hope this helps. Ian

Shortening the Bay Platform As mentioned above, I've found it necessary to shorten my bay platform at the station. It was originally laid long enough to 'look about right'. Turns out it's too long, and needs to be shortened to properly align with the end of the platform building (well, one canopy panel beyond the end of the building actually). I marked out the section to be removed with a marker pen and cut the rails: Then I used a disc cutter in my dremel 'clone' to cut through the ballast Because there is 3mm of foam underlay under the tracks, the ballast 'cutting' was quite straightforward. A craft knife did the rest of the cutting down to the baseboard. I could then insert a knife under the underlay (helped along with a thin steel ruler) to release the track from the baseboard: I was surprised that the whole thing came off in one piece. Not only that, it is quite strong and resists any bending or deformation. Looks like my glued ballast is more robust than I thought! Meanwhile, I cut a rectangle of 18mm plywood to create the platform 'extension'. It took some time to craft it into the required shape on my disc sander. I then glued-n-screwed it to the platform plywood. Here it is back on the layout, with the coping stone 'extensions' already glued into place: Now I can, finally, glue on the 2mm greyboard 'topper' to the plywood and cut out the rest of the footprint for the platform building. Ian

Oh yes, should have noticed that. So, not a T4 bogies then. Again, close 'but no cigar'. As you say, too many dampers. The bogie in my photo seems to be a 'lash up' between a T4 and a BT35. Very weird. Hopefully someone will be able to come up with more details. Ian

Many thanks to @keefer and @25kV for their replies. Following the @keefer link I noticed the lower photo of a T4 bogie. Closer examination seems to imply this is the one on my original photo (?). A bit of a Google search for the T4 bogie came up with "IIRC the 158s were built with the T4 bogie - a lighter weight development based on the BT10 and the suburban bogie first used in the Class 313s.". Now if that' true it's one hell of a good suburban bogie if it can operate at 125mph in service. Ian

I have this photo I took in 1981 at Doncaster of a pair of Mark 3s on an HST showing the bogies. The one on the right is a 'normal' BT10 bogie, but what's that one on the left? Ian

Platform Covering A few posts back, I drilled some holes through the platform plywood (18mm thick) in which I plan to insert some styrene rods to 'represent' the columns under the overbridge. All was well, until I realised that once I'd installed those columns, retrofitting the 2mm baseboard 'topper' (to make up the full 20mm height required) and the paving 'texture' was not going to be possible. Well, not with my skillset anyway. The 2mm 'topper' was always planned, and you'll see my logic later below. So, it was time to get that 'topper' installed, using simple 2mm greyboard. This was glued onto the plywood using clear PVA glue and left to dry/set. It was then 'trimmed' around the edges to achieve the correct shape. The holes for the columns were easily drilled through the 'topper' from the underside of the plywood (I'd drilled right through previously). With that done, I very carefully placed the platform building back onto the platform, and verified it's location in relation to the overbridge. This is important in order to ensure the gap is 3 standard glass canopies wide. With the location marked, I could cut out the 'topper' for that area: Now you can see my logic, the buildings will be 'embedded' into the platform in a (vain?) attempt to hide the joins. Before placing the platform building: After placement: Yes, the platform building was constructed 2mm higher (err, deeper actually) to allow for the embedment. The station platform is in 3 pieces, because it extends over 3 baseboards, and I also managed to add the 'topper' to the ramped end section: That just left the middle section of the platform to be covered with the 'topper'. However, this can't proceed because I need to make the bay platform ~10cm shorter and convert that length to more platform. That'll be the next job on the list. Ian

That's what I had to do as well. Install the fishplates as normal, then flow solder into the foot of the fishplate to affix it to the rails. Then I could cut the rails 'at' the baseboard join, cutting through the whole rail/fishplate assembly. Ian

Dave, Have you considered the option of selling it all off at a model railway / toy fair? I've seen this done a few times (at the Doncaster train fair), and the people on the Stands reckon they get more money than using an Auction or a large model railway shop / Dealer. Ian

That's some mountain! Going to look mighty impressive I'm sure. Ian

Paul, I always found that as long as I'd planned and drawn everything out in advance, things weren't as bad as I expected. Probably because I'd know what I was letting myself in for! Complicated I can deal with; it's when the unexpected appears that I had problems. Ian

You mean this one, as I photo'd in 1983 at Merehead Quarry: Ian
