Class 87 for Caldew


ClikC

2,764 views

As a break from my recent projects, I decided to start a long overdue project, a Class 87 re-motored and converted to P4.

 

An old Lima 87 was picked up for about £25 on Ebay, and with Rails of Sheffield having the new Heljan 86's on offer for varying prices, I picked one up for £84.50. Also had the benefit of allowing me to evaluate a Heljan 86 offering, and to be able to make a more informed opinion on it's viability for re-motoring Hornby's much better 86's and Hornby/Lima class 87's.

 

Unfortunately due to the thickness of plastic the Hornby 86 is molded in, it won't fit on the Heljan chassis without considerable work. The good news, the Lima 87 body slips on easily once the body mounting lugs have been removed (I chose to drill vertically down the lug to remove it tight to the underside of the body roof). But some work is required to make the body sit flush, due to the components on the Heljan circuit board. I chose to make with the elbow grease, and set to the inside of the body armed with course emery paper and a grinding tool in a mini drill. A mill would make light and accurate work of this, but by far the easiest option would be to dispense with the Heljan circuit board, and make your own smaller one.

 

The chassis was stripped of everything but the battery box and air tanks (I'm not sure on the air tanks, i really need some photo's of the underframe on the prototype to make sure everything is situated right). Wheels were replaced with Alan Gibson 3'8" steel tyre'd P4 disc wheels.

 

Here are some photo's of the work completed so far, pictured with a Bachmann Mk1 Bg and Airfix Mk2D.

As you can see from the above photo's, i've only done the one side so far. Hornby class 90 bogies shrunk to the correct 43-mm (for 4-mm scale) axle spacing, and I've started to rebuild the underframe with a mixture of Heljan parts, and parts cut from the old Lima underframe. The flexi-coil springs need adding, but need filing down to fit (they are a bit to tall on the Lima 87). Eventually I aim to have full working primary coil suspension and working flexi-coil secondary suspension, but thats probably better listed as a 'pipe dream'.

 

I also need to figure out what I'm going to do about the GEC (AEI) cross-arm pantograph, which I guess is going to be a scratch build, or a very fiddily to design and build etch. And I need to find some Hornby class 50 MU jumpers, but thats all detailing work really.

 

This 87 is destined to become 007 with sister 014 to follow later, the plan being that these two will feature working a double headed frieghtliner service.

 

With regards the use of the Heljan 86 for re-motoring, I'll be doing it again but much much later, when they are going cheap on ebay. It was a tough decision, I want to support 4-mm scale overhead electric loco's (both kit and RTR), but I wish that these offerings better reflected the look of the prototypes. Hopefully the forthcoming Bachmann class 85 will do what the Heljan 86 has not. I also find the Heljan method for bogie mounting leaves them a little to stiff for my liking, so for future 87's and 86's, I may go with stretching the future Bachmann Class 85 chassis's.

 

As always, comments, suggestions and criticisms welcomed.

 

Regards

Interesting project Matt.

 

The Lima 87 body always looked pretty good to me apart from just one issue - the windscreen frames. I can't put my finger on whether they are the wrong dimensions, or whether they stand a little too proud, but summat just doesn't do it for me.

 

i wonder if anyone has checked them with a 1:1 class 87.

 

Great stuff though Matt and good that someone remembers that 87s shifted a lot of freight at night. 4S50 Dudley-Gushetfaulds was booked an 86/0 and an 87, as was the return 4M51. these locos came off Down Euston-Wolverhamptons after they'd deposited their stocks at Oxley, both coming separately light to Bescot where we multied them - 87 on the inside and 86 on the front.

 

The return 4M51 was just the same. We split them and sent them both to Oxley for Up Londons.

Funny you should say that about the windscreens Phil, I was looking at the picture above earlier and trying to work out why it din't look quite right.

 

Again, I can't quite put my finger on why, but something doesn't look quite right.

 

It's looking good Matt, I never knew that the Hornby 90 bogies were too long, are they out by much?

What did the Dudley legs Phil?

Hi Phil, and Pugsley.

 

Yeah the cab windows have been bothering me too. While no doubt my photography hasn't helped show of the model.

 

Main points to me seam to be;

  • Main center dividing pillar is to thick.
  • The moulded cab window surrounds too curved, should be flat,
  • The cab roof has a far to much sharp 'porch' going on, and should be more subtly curved. This and the bad lighting in the photo graphs cause quite a bit of shadow.

I'm also wondering if the whole cab window unit is inset a little too much into the rest of the bodywork, this seams especially the case near the main cab-side corner pillar. I expect a nice etch coupled with some laser cut glazing from brian hanson would drastically improve the model. As i'll be seeing him this weekend I'll be sure to give his arm a good twist.

 

Otherwise, I think the Lima 87 is pretty damn good. Some filling and a bit of wet and dry will improve the cab windows no end I expect, in the same way that a bit of filing on the Bachy 47 to get more of the 'sad eye's' effect improves the model no end.

 

With regards the bogies, the Hornby 90's come in with 44-mm axle centers, so only 1-mm out from the prototype and considerably better than the 40-mm axle spacing on the Hornby 86 bogie.

When was this Phil? My period is May 1974, so only the 87's worked in true multiple. But many services were double headed, at least through Carlisle. From the notes supplied to me by Steve Rabone, all 50% of the 87's heading north on a double headed FL service are back to Carlisle within 6 hours on another service. But then 1974 WCML workings were pretty damn intensive!
