Class 37 cast - fabricated bogie confussion

[vac_basher]

Forgive me for asking such an elementary question, but what exactly is the diffrence between a cast and a fabricated bogie on a Class 37

To me the bogies on the ol' tractors all look the same....

 

From what I understand so far, both Bachmann and ViTrains do only the fabricated type. Whereas Hornby do the cast type on the Class 50 (still looks the same as the fabricated type to me! ), which with some modification can be addapted to the Bachmann and/or ViTrain Class 37s.

 

Looking at a (real) Class 37 how can I tell what sort of bogies it has?

 

Thanks in advance.

Mystery revealed!

Fabricated ones have a kind of lip (highlighted), whereas the cast ones are smooth sided and of a slightly diffrent shape at the ends

(Wish I'd never found out though - the model I'm doing has the wrong bogies! )

Bachman also do/did a cast bogie moulding. I dont know if its still available though. kev.

Bachmann's EWS 37419 from their first batch carried one fabricated and one cast bogie to replicate how the prototype ran for a while....

If we weren't amidst a recession (Will this ever end? ) I'd probably have gone and bought two 37419's just for the bogies

LOL - your only option for you can almost guarantee that if you asked: "that spares item is currently out of stock!".

Does anybody know if Bachmann Deltic bogies could be used as a representation of the cast kind on a Bachmann Class 37 ?

I fitted some D*lt*c bogies to my 37423. They don't look quite as chunky as the original 37 bogies. If you do, you'll have to redrill for the footsteps - or used an etched version.

 

I've converted fabricated into cast bogies on a couple of recent models by using a sharp (i.e. new) scalpel blade to cut off the "flange" of the fab bogie and then scraping along the edge to round it off slightly. Tedious, but cheaper and quicker than waiting for the Bachmann service department to send the wrong part first time.

 

Cast on the left, fabricated on the right. The modified bogie still needed a quick coat of black.

Looks ok to me sir.
Do the wheels line up as they should with the axle boxes?

They do for the modified type in the pic, as they're original 37 bogies........

For me its the opposite way round, as I need fabricated bogies for my Deltic, The frames should be a straight swap as they use the same methods to clip onto the gear towers

 That said reading further up this thread, I emailed Bachmann (The service department) about the bogie spares, they had them in, but they havnt replied to my email saying I want some!

The deltics were built with fabricated bogies but very quickly fitted with new cast bogies as the fabricated ones were cracking, they kept the cast bogies until withdrawal when the cast ones were fitted to class 37s being overhauled, any Deltics which were preserved had the cast bogies removed and fabricated bogies fitted.

 

So unless you are modelling a Deltic as delivered new or as preserved then it will have cast bogies.

Note the lack of brake cylinders on the 37.

Thanks everybody. Excellent info!

True at present, but the DPS have just bought a pair of cast bogies, which when re furbished, will go under Tulyar...

The Deltics had fabricated bogies from new up until 1965. As I recall D9019 was the last to be swapped.

 

There is one other exception to the preserved Deltics with fabricated bogies rule and that is 55002 which retained its cast bogies when it went to the NRM.

 

If I may say, the bogie under the Class 37 looks as though it has been stripped of some parts. There are certainly brake cylinders on there usually.

 

Best wishes

The 37 had the brake  cylinders etc removed to prevent water damage, the owner has since had a falling out with the railway (as have I) so the future of the 37 is a bit up in the air at the moment.
