Why do you think Bombardier vs. Alstom? I'm sure Breda and CAF will be in the mix too, they always are.
The big reason I think Bombardier vs. Alstom is because both companies will attempt to outbid each other and have both been securing major projects lately. Bombardier will probably want to get some cars in the Metro since they are the #1 producer of cars in the world. They are on a roll lately and would want to further boost their worldwide presence. After winning the major London Underground project to produce nearly 1,200 cars and the new CityFlo signalling system (supplied by Alstom in the past), the Singapore automated metro project (also supplied by Alstom in the past), the New Delhi project to expand the fleet (supplied by Hyundai-Rotem previously), the Toronto fleet expansion projects (both streetcar and subway), and the Montreal fleet replacement project, Washington will look great in their portfolio.
Alstom will want to further their position as well in the top 3. Washington is 1 of their biggest customers with the 2/3k rehabs, 6k cars, and the signalling system. Then add NYC with over 600 cars being produced in the split order and the potential R-179 and R-188 orders, Atlanta sending them rehabs, and their major european projects such as the Paris Metro. Plus Alstom sued Bombardier to be allowed to bid on the Montreal contract since Quebec was and still is attempting a sole-source contract with Bombardier. Alstom will want to stay in a top 3 position and boost themselves to being the leader in the US.
Breda has not been doing too much here in the US lately except trying to take care of their screwed up projects. Their Boston Type-8 LRV project is almost complete after nearly 10 years and lots of fighting with the organization. The Los Angeles P2550 LRV project has been plagued with problems (leaking HVAC systems, door problems, propulsion problems with the Ansaldo traction drives used (that have never been used here) which is causing that order to be about 2-3 years behind currently. The most recent successful and on-time project for Breda was down in Atlanta where the 100 cars were finished on-time, on-budget and have been performing well. Alstom got the nod to do their rehabs on all of the older cars however.
Kawasaki has a lot of work lately since they are doing the orders on the R160 and PATH contracts. The only issue with them is that their Yonkers and Lincoln plants can only handle up to around 350 cars at a time. Traditionally they usually dont bid on a project with over 300-350 cars at a time. As much as I would like to see them build cars for Washington, I doubt it will happen but they could definitely win it.
I think CAF's problem with the 5k project was working with AAI, which caused their cars to have extensive problems. Also, Metro rushing the order didn't help anything with the Branch Ave extension passenger traffic being way beyond expectations. Metro was scrambling to put together additional 6 car trains from the float used in case of breakdowns or other problems. However now that AAI's transit division was bought by Alstom (during the Baltimore Metro rehab), and that CAF established their own plant in Elmira, NY, it could be a night and day situation. They seem to have produced very good cars for other systems including Rome, which is traditionally supplied by Breda.
Siemens may be looking at the Washington Metro as another big project to further grow their presence in the US. Even though they are the largest supplier of light rail cars in the US, they are just breaking into the US HRV market with their successful Boston Type 07 cars. These cars have been performing very well since being put into service earlier this year. Even though there were some issues that caused delays, the final product is considered excellent. Their major experience is overseas in Europe and in Asia, but have the facilities in the US to make a large scale project work. Even though I don't expect them to win the bid, they are mad about losing the Toronto contract (Toronto decided on a sole-source contract with Bombardier), they may look to boost their portfolio.
Hyundai-Rotem...don't get me started on that. Most of their projects have been messed up and their way of getting to the top is to severely underbid projects and make agencies pay for it later. If they were banned from bidding in Taiwan on any projects because of severe quality problems, being second-guessed by Hong Kong after screwing up propulsion and door systems on the K-cars, and just losing the New Delhi option orders to Bombardier after building the initial cars, there obviously is a reason. Let's hope that the powers that be at Metro see that for what it is.
Gotta love Alstom. Every year on opening day of hunting season, it is a paid holiday!
