I should have ammended that. I meant slight improvements over what is currently the state of the art in LRV/trolley/tram construction out of Siemens, Bombardier, Alstom, or even Skoda. Aesthetics aside, what would be gained by from an operational perspective in building a new low floor PCC which a Combino, Citadis, Flexity or Astra would not provide?
Why does a trolley have to look like a spaceship?
Because the spaceship look is at this point the cheapest, yet most aesthetically pleasing shape possible. It allows for slab-sides which are extremely cheap to build; large, flush fit windows (admittedly these likely add cost, but are worthwhile from an aesthetic perspective); and some composite parts to break up what otherwise would be a very boxy creation. The Europeans actually have a wonderful way of using the same frame to produce LRVs for different cities which manage to have different looks yet are all nearly mechanically compatible. The Alstom Citadis design in particular does this quite well, systems in Lyon, Paris, Bordeaux, Orleans, Montpellier, Grenoble, Nice, and many other cities use Citadis trams and in most cases they all look slightly different. Through modular parts Alstom can turn out an LRV specialized to a given customer with little difficulty. The Bordeaux Citadis have a surface mounted 3rd rail system to avoid 'ugly' overhead wires in a historical part of town, while the Nice Citadis have an NiMH battery system to provide power through a similar area. The Regio Citadis is a dual voltage LRV designed to work with both 750vdc and

If you brought it here to the states, got waivers from from the FRA, and tuned the transformer slightly you'd be able to run the damn thing up and down the NEC. If you had to point to a "modern PCC" the Citadis would be that and more in terms of the concept and execution of a standardized LRV to drive down the cost of infrastructure improvements. Siemens and Bombardier both offer the exact same range of products, but their (respectively) Combino and Flexity brands don't have quite as much emphasis on altering the aesthetics as the Citadis does.
Sure in the 1940's they were hand shaped, but today a good shop like Bombardier has things like brakes and presses to mold metal into any shape you want. The automakers certainly don't have issues makeing bubble cars, why not for a trolley?
No, back in the 1940s they WERE using those presses, dies, and such to turn out the PCCs. They were trying to produce a trolley which could be built through the same methods then being used to drive the cost of automobiles down to get away from the more labor-intensive trolleys being turned out by Brill, Birney and such prior to the PCC. Today unless you have a very large order the cost to produce that tooling just wouldn't pay off. As such you'd have to build the cars largely by hand and a hand-built PCC would be extremely expensive, what with the curved metal and such to be shaped and formed.
Additionally, most cities don't seem to be particularly picky about what trolleys they get for their vintage trolley line. They just want something which looks vaguely like the old pictures of the city, and call up Gomaco to do a replica Brill, Birney or other early design, most of which predate the PCC because many systems didn't make it to the PCC days. Only San Fransisco and Kenosha specifically run PCCs, and then San Fran has found the earlier Milan Peter Witts to be excellent cars in their own right, while Kenosha likely doesn't need any PCCs. Every other system in the country is quite happy to take their Brill-lookalikes from Gomaco and run them back and forth while pretending they have a light rail line.
I'm not saying manufacturers should be churning out PCC lookalikes, but it would be nice to retain certain features (single headlight for example), while having modern features at the same time. Can't there be a happy medium between Classic streetcar and spaceship?
What features would you retain? The tiny size? the tiny windows? The generally dark, cramped feeling? The hard to defog front windows? The PCC is a dead end and any attempt to resurrect it is just reinventing the wheel with a different hubcab. Dual headlights actually do serve a purpose, they provide a more even lighting area over which objects will not be caught in the blind spot of something placed before the single headlight. You don't see auto manufacturers going to single, center mounted headlights, so why would LRV makers want to do so?
Why insist on a PCC derived design which would cost millions to develop when there is an LRV design perfect for Philly which can be taken off the shelf and operated here? Aesthetics is a rather poor reason to go back and reinvent the wheel.
