What's the difference in Class 350 sub-classes?

[whhistle]

Are there major differences in the sub-classes of the 350s?

I know the difference between the /1 and the /2 are seating arrangements but what about the /3 and /4?

Brief summary.

350/1 owned by Angel 2+2 standard seats covered in (threadbare) blue upholstery; converted to be 110mph capable.and have dueal voltage capability - ac and dc
350/2 owned by Porterbrook, 3+2 seats in standard, green upholstery, 100mph capable
350/3 owned by Angel, as per 350/1 but 110mph capable from new and no train manager's office and 25kv only as built.
All operated by London Midland

350/4 owned by Angel, as per 350/3 but seat layout more spacious.
Operated by TPE

The /4 layout is near enough the same as /3 except First Class. It's certainly not more spacious!

 

[Pumbaa]

An extra toilet on /4, plus trolley storage area and 1st has 2+1.

And 350/3 is in the same interior colours (green) as 350/2.
350/4 is in TPE colours (blue) with horrific FirstGroup toothpaste external stripes.
There was some view early on that the 350/3 had different driver functions in the cab (DAS was it?) which delayed their entry into service.

350/4s now have the new TPE branding.

There are numerous small differences between the types but a the most obvious are....

/2 is the only sub class not cleared for 110mph.
/4 is the only sub class to feature speed set.
/3 and /4 have the new TPWS2 unit.
/3 and /4 have fire protection system fitted.

The /4 has 3 toilets instead of 2, slightly different seating layout for long distance running and also features a catering area/trolley store in the TC car.

350/1s were originally going to be DC 450s. They were delivered as dual powered 350s in 'neutral' branding so that both Central and Silverlink could share them.
/2s were built as designated AC units with 3+2 seating to replace 321s.
/3s were built as designated AC units with 2+2 seating to LM specification.
/4s were built as designated AC units with 2+2 seating to TPE specification.

And it was a modified Dynamic Lines not Toothpaste.

Not sure if it is the case now, but TPE 350/4's seemed to have reliability issues, compared to the 350's used by LM

 

[Des Iroman]

350/4s have a 'speedset' function too.

In layman's terms, what is that?

In layman's terms, what is that?

It's much like cruise control on your car, and the various train manufacturers have varying ways of doing it. Unfortunately I'm only familiar with the Bombardier and Hitachi versions and so can't be more specific with regard to 350/4s.

Reach the speed you want, quickly shut off and reopen the handle to full and speed set activates. A lamp flashes to confirm this. The /4 also governs itself to 110mph.
