As I recall a lot went into service with power reduced so that they did
not trip out the sub-stations so longer journey times for a time. One of
the first big projects for Network Rail as well. As you say fancy
ordering trains then not thinking about the infrastructure needs one of
the many benefits of the flawed privatisation.

I heard of other problems with out of gauge DMUs elsewhere.
One of the more doubtful features was independent sub-contractors not
supervised properly, and not making sure the loading gauge was correct
after working on the track.

Interesting story about when the Networkers were introduced was that
they were designed as wide as possible with mm clearances in some
tunnels so BR solved this by gluing the ballast. In later years
maintenance wasn't so great so some of the units got some scrapes on them.

The problem was with the TOCs, using main designers and contractors
who had f*ck all experience of building stock to the UK loading gauge,
whilst those workshops that did (over a 150 years in some cases...)
sat idle or closed... As you say, the price for a botched
privatisation.

I would not call Bombardier (inheritor of BREL at Derby) and Alstom
(inheritor of Metro Cammell) companies with no experience of UK train
design. The problems for Bombardier was getting the GTO power system in
their electric trains passed for safety and some problems with engines
that power the turbo stars. For Alstom the new French owners ignored the
UK designers and insisted on using continental bogies under their
Cordias and some poor design of the placement of engines. Ironically
they did not experience many problems with the GTO power system on their
electric trains but still had it with the bogies. The TOCs don't
directly specify the trains as they are not the owners this is down to
the ROSCOs who finance and order the trains. The DfT rail seems to be
going back to the BR way of ordering trains but trying to keep them in
the private sector, have a look at May's Modern Railways Informed
Sources article. You can also visit

presay of May's article.

The parent company was the problem, not the workshops, they were non
UK companies - another part of the botched privatisation, BREL should
have been kept intact.

Exactly, they didn't understand the UK railway system, it's safety
regime, and it's 'culture'.

They order the stock, if they refused to order from non UK owned
railway workshops / companies...

As I said, the botched privatisation...

They have to, there is no public sector!...

It could never have stayed as BREL for a number of good reasons:
1 Not large enough compared with international competitors.
2 Only strong in coaching stock with no in-house expertise in power
systems. Anyone remember the international train BRELs attempt to break
into the international market. No presence in locomotive construction or
wagon construction.
The ownership changed in the late 80's before the railways themselves
were semi-privatised. Before that the UK market was distorted with the
quasi subsidisation of BREL which resulted in cost cutting in
competitors products notably the 156 and mk4 coaches.

All the UK companies had the same problems when the Networkers were
introduced and the Dutch when the 323's were introduced. The only
peculiarity was the third rail DC AC track circuits.

Part of this was the order delay introduced by privatisation, York works
closed because of this, and then the failure of Alstom to make their
EMUs and DMus to work reliably quickly so we got German trains that
compared with UK trains worked out of the box with no major problems.

The last is more of an accounting trick to keep the cost off of the
public account than anything else.
