Apologies if this is in the wrong place ( i did look but couldnt really see a rolling stock bit) but i was wonder if people could furnish me with some train lengths to aid planning.

I'm primarily after

2+8 Hst
36 Wagon MGR plus loco eg 56
37/47 etc plus 5 coach
37/47 etc plus 8 coach
158 2 car length
loco plus 10TEA bogie tanks

As i havent got any stock it does make planning a little difficult to do so any help would be appreciated.

Thanks

Rather than list the lengths per train type use this :

Locomotive (Class 37 / 47) = 14cm
Locomotive (Class 56 / 60 / 66) = 15cm
HST Power Car = 13cm
Mark 1 / 2 coach = 15cm
Mark 3 coach = 17cm
HAA wagon = 6cm
HTA wagon = 12cm
TEA wagon = 12cm

Thanks, that was the other way i was thinking of doing it.

I can give you the exact length of a 2+8 HST 




Paul

Thanks, thats perfect. And in the right colour scheme too!

Richard

Of course it's the right colour scheme, is there any other???  


EDIT: OK, BR blue 'n' yellow or NatEx silver/white at a push ;o)

I currently have three HSTs, INTERCITY, GNER, and Virgin Trains
However they are all different lengths, even the two 2+8

Probably coupling length. Amazing how a few mm can add up. No i maintain swallow is the only livery hsts should be seen in!

I am a bit puzzled by "train lengths".

A few months ago i brought the "farish colliery set", class 14 loco + 3 10ft steel-sided mineral wagons.

I was then given a whole load of "peco wagon kits" by a club member; 2 (10ft) bolster wagons, 2 (10ft) steel-sided mineral wagons, 3 (10ft) plank-sided mineral wagons & 1 (15ft) low-sided plank wagon.

Since then i have been trying various combinations of wagons but the loco only looks right with the following combinations.

Loco + 3 wagons (from the set) or loco + 5 wagons (peco 10ft) or loco + 1 (15ft) low-sided plank wagon & 2 (10ft) bolster wagons.

Is it just me or could there be a reason why only these combinations look right?

Hi Reuben,

I am sure this is just a perspective thing in that the Class 14 is a relatively small loco so to see it pulling a long train seems to stretch the imagination a bit. Maybe someone will know a prototypically correct length train for that class.

Hi Reuben, for only 3 to 5 wagons this loco seems a bit large. There are pictures around showing class 14 with more wagons.

Should the train length be related to the tractive effort of the locomotive?  I assume that there is some sort of compliation around rolling resistance, gradients etc. but the load that a train can pull must be less than its tractive effort isn't it? 

So if you google the load + Tare weight of you wagon(s).  You also google the total tractive effort of the locomotive.  If you divide Tractive Effort by Wagon weight it should tell you how many wagons you can pull...

All you experts out there is this basically right?

On Britsh rail it's hard to tell. They were essentially ordered to replace the army of pannier tanks just at the time that
- all the small mines closed killed by mechanisation and scaling
- all the big mines went (or were dragged) into MGR operation not little rakes of wagons
- the unions and BR managed to get as far as 'ok the guard can go in the back cab if there are two'
- everyone realised that freight should be moving at higher speeds

So they pretty much arrived and went in the bargain bin where the NCB and British Steel had lots of them, because they were slow (40mph max) and under powered for anything useful on BR. They were only 650hp and quite light. How big a train anything can haul is of course as much down to weight, and braking as anything else - plus the gradient on the line.

On the Gwili they seemed to have no trouble shifting 4 mark1s and an 03 hanging on the tail. On the Dean Forest they work similar loads and that's pretty steep. Not sure what the translates to in wagons, you'd have to look at the tonnage and if they were full/empty.

I've not seen any useful images of them on the NCB to count wagons but that would probably give a better idea since the NCB don't appear to have believed in underloading



The other major low power diesel class was the class 20s but instead they were pretty much tied permanently as pairs and used as a 2000hp 2 cab loco, and proved to be incredibly reliable (and still are).

I think i understand what you guys are talking about and thank you for your replies.

I tend to use the following as a rough guide for train length.

I have 2 pieces of "peco double straight track" mounted on a small length of wood,
each track section will hold "1 coach" or "5 - 6 wagons", depending on wagon length.

So i tend to use 3 wagons with a shunter (class 03/04/08), 5 wagons with a small loco
(class 14 - 33), 10 wagons with big loco's (class 37 onwards). Then for coaches i tend to
use 5 in a rake.

Perhaps its a visual thing but these lengths seem about right to me.

Reuben.

It was said of the 14s during their time working the docks branch in Hull, that it only took one of them to move any train you wanted however it would need at least three of them to stop it!
