In the original caption.

 

"Officer's Saloon DM45029 is shunted clear of the Main Line at Aberystwyth by 2-Car Parcels Unit formed of Class 116 DMBS 53072 and Class 120 DMBC 51785.

 

"Due to a ban on locomotives working along the Cambrian Coast, special workings like this were carried out by Class 128 DPUs or converted Parcel Units."


I should have clicked on it. Sorry, thanks though.

It was the extra large van on the 120 that caught my eye.

IIRC these were DMBC vehicles which lost the two second class seating bays in order to make a larger van area with a second set of double doors. The first class seats were retained, so they became DMBF.

I think this was done when used in the north of Scotland, inc. Aberdeen-Inverness

As if a Peak didn't have enough wheels and tons already. Those Sulzer horses must have been ready for the glue factory after shifting all that lot AND a long train of iron ore!

Wikipedia states that they were needed due to the lighter weight of the diesel locos compared to the steam they replaced.

Really? The Peak has way more weight on it's driving wheels than an 8F or 9F.

Crappy brakes more like:D

Very interesting, thanks for that.

Pretty sure they were renumbered; the DMBCs on the ones used west of Swansea were 507xx, not 517

Had a chance to look up railcar.co.uk for the details:

Or, it could be that the Peak was capable of pulling far more tipplers than an 8F or 9F. 

 

As an example, the change to diesel traction on the GN&GE meant that the only limit on the length of loaded coal trains was the capacity of the sidings at Whitemoor yards.

The limits on load for goods trains in steam days were always:
 

1. What the engine could brake

2. What the lay-by sidings could hold.

 

High speeds were not desirable due to the limited braking ability so the steam engines weren't built to achieve it. What the engine could pull at low speed was never really a problem, they had the low speed torque but not the high speed power - different things. Unfortunately, the diesels did have the high speed power and some previously sane drivers took advantage of this, then found that stopping again was a bit more of a challenge than just pulling the controller around had been.
