I have found something a European city does worse than the United States in public transit. Paris has just announced its new bilevel design for the RER B, currently the only line running single-deck trains due to restricted clearances. The new double-deckers, dubbed MI 20, are expected to cost 2.56b€ for 146 trainsets, each 104 meters long, for a total of 168,600€ per meter of train length.
I’ve criticized Paris’s use of double-deckers in the past. The cost premium for a double-decker, usually around 25-50%, at best matches the gain in seated capacity, and leads to other capacity problems with access and egress, which are of especial importance on urban rail like the RER. Not for nothing, bilevel trains are not used in Tokyo except for the occasional first-class car (“green car”), which is less crowded by design than the legendarily crowded subway and regional rail cars.
However, this is a lot worse than the usual premium. The only comparably expensive bilevel I can find is the Stadler KISS order for Caltrain, which at $230,000/m for the base order (and only $160,000/m for an equal-size option) comes at a large premium over usual KISSes (both around 130,000€/m) due to client interference and micromanagement coming from low competence by American railroaders.
But the KISS is a high-performance train, at the expensive end in Europe, too. Moreover, it is fully bilevel, whereas the MI 20 has a mix of single- and double-deck cars, with high-platform boarding. Comparable split-level trains go well below 130,000€/m. Canalblog has a compendium of recent Coradias: the single-level example for Milan is 6.25m€ per 84-meter train, or 74,400€/m, and the mixed single- and double-deck examples are 96,700€/m in Luxembourg and 117,600€/m in Germany. The mixed-deck Siemens Desiro HC has a range of costs: its RRX order is 1.7b€ for 82 150-meter trainsets, which is 138,200€/m, but a smaller order for the Berlin RegionalBahn is 300m€ for 21 six-car and 2 four-car trainsets, or 89,600€/m, which is a high but not unheard of cost for a single-decker, let alone a double-decker. The Desiro HC is being delivered to Israel as well, at a cost of 900m€ for 60 trainsets totaling 330 cars, or 109,100€/m.
There’s nothing special about Paris that justifies such a cost – the highest in the world so far, even beating the Americans. Rather, the problem is most likely that Paris thinks it’s special and won’t buy a standard platform. Canalblog points out that the Coradia Duplex formed the basis of the X’Trapolis, currently delivered for the RER D and E – and the X’Trapolis’s first tranche spent 29% of its budget on design and engineering, driving the cost up to a stratospheric 21.83m€ per train of length 112 or 130 meters. Even averaged over the entire order of 255 trainsets, at which point economies of scale kick in and the bespoke design is less harmful, the cost is 121,400€/m, which is 25% more than the more standard Luxembourg design.
Update: Clem Tillier asked me about Madrid’s recent Cercanías order. This is a mix of Stadler trains and Coradias, both mixed single- and double-deck; the Coradias, using the same platform as the Paris X’Trapolis trains and built in Spain rather than in France, cost 1.447b€/152 trainsets, or 95,200€/m, and the Stadlers, mixing KISS and FLIRT technology, cost 998m€ for 24 100-meter trains and 35 200-meter trains, or 106,200€/m.
In a megacity like Paris, it’s tempting to think one is special and must have special equipment. But the resulting high costs are particularly damaging in such a city. The RER B runs every 3 minutes at rush hour, which means that high rolling stock costs are proportionally a bigger problem than on a less frequent system. The cost premium of the order over standard single-deck trains is a factor of around 2; half the cost is 1.3b€, which would be enough to build some necessary tunnel extensions, like quad-tracking the combined two-track tunnel for the RER B and D between Châtelet-Les Halles and Gare du Nord, or if RER investment is not desired then around 6 km of tunnel for Grand Paris Express after the latest cost overruns.
France needs to let go of its pride and recognize that Paris is merely the largest city in the Union, with the same standards and regulations as the other 440 million of us who do not live in Ile-de-France. Vanilla Coradias and Desiros that work elsewhere should also work for the RER, with minor tweaks to take into account high platforms and the loading gauge, both of which the vendors are experienced in dealing with due to common intra-European variation. The people who sign extravagant contracts may feel special about the train design, but the passengers who end up not getting the investment the cost premium would have gone to are going to keep feeling packed on rush hour RERs. The region ought to do better and hire managers who are better than this.
